216 * tests/base.at (AC_CACHE_CHECK): Try symlinked cache file.
217 * doc/autoconf.texi (Cache Files): Leftover temporary cache

328 AC_HEADER_STDBOOL: avoid spurious failure with modern xlc
329 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Move the "bool e =
330 &s;" test into the main program, as C99 might plausibly be
331 interpreted as not requiring support for this construction in
332 static initializers. Remove the "#if defined __xlc__" stuff, as
333 the bug is not present in recent xlc implementations, and they
334 reject the test for other (valid) reasons. People using ancient
335 xlc versions, if any, are suggested to update to fixed versions.

350 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Drop gcc (and by

352 rather than merely testing for a compiler extension.

6987 forks when sanitizing PATH. Always output machine information,
6988 not just when atconfig was located.
6990 Add 'testsuite -C dir'.
6991 * lib/autotest/general.m4 (_AT_ARG_OPTION): Move missing argument
6993 (AT_INIT) <PARSE_ARGS_END>: ...here, since -k always takes
6995 <DEFAULTS>: Delay computation of variables based on $at_dir...
6996 <PREPARE_TESTS>: ...to here, since -C can change $at_dir.
6997 <TESTS>: Re-invoke via absolute name, since -C may be in effect.
6998 <PARSE_ARGS>: Parse new option.
6999 <HELP_TUNING>: Document it.
7000 * tests/autotest.at (Choosing where testsuite is run): New test

7013 2008-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7015 * doc/autoconf.texi (Particular Programs): Do not mention the
7016 Autoconf version in which the AC_PROG_INSTALL change was done.
7017 Suggested by Paul Eggert.
7019 2008-01-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7021 Fix --help=recursive with multiple AC_CONFIG_SUBDIRS.
7022 * lib/autoconf/general.m4 (_AC_INIT_HELP): If, for recursive help
7023 mode, we change to the source directory, also set $ac_pwd so we
7024 do not go back to the build tree for the next config subdir.
7025 * tests/torture.at (Deep Package): Extend test to contain two
7026 config subdirs on the top level.
7028 Fix parallel `maintainer-check'.
7029 * Makefile.am (maintainer-check-tests): Depend on `all'.
7030 Use `$(MAKE) $(AM_MAKEFLAGS)' instead of plain `make'.
7031 * tests/Makefile.am (maintainer-check-c++, maintainer-check-posix):
7033 (maintainer-check): Serialize the testsuite runs.

7057 2008-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7059 * tests/Makefile.am (noinst_SCRIPTS): Renamed from
7060 check_SCRIPTS. Building the wrappers for `all' allows help2man
7061 to use them for the manpages.
7062 Report by Benoit Sigoure.
7064 * bin/autoreconf.in: Discard stderr for $autoconf/$aclocal --help.

7078 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7079 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7080 (m4_require): Use m4_do, not m4_join.
7082 Fix some whitespace tests on cygwin.
7083 * tests/tools.at (autom4te and whitespace in file names): Restore
7084 font-lock. Create $TMPDIR before it might be used.
7086 Fix spurious testsuite failure with M4 1.4.11.
7087 * tests/local.at (AT_CHECK_M4): Cater to new m4 error message.
7089 Optimize AC_REQUIRE.
7090 * lib/m4sugar/m4sugar.m4 (m4_expansion_stack_push, _m4_defun_pro)
7091 (_m4_defun_pro_outer, _m4_defun_epi, _m4_defun_epi_outer)
7092 (m4_require): Avoid extra macro calls.
7094 2007-12-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7096 * tests/torture.at (srcdir): Fix quoting.
7098 Do not pass top_srcdir to configure scripts in testsuite.
7099 * tests/autotest.at (srcdir propagation): Copy install-sh to
7101 (my only test): Drop setting of `top_srcdir'.
7102 * tests/base.at (Input/Output): Likewise.
7103 * tests/local.at (AT_CONFIGURE_AC): Copy install-sh,
7104 config.guess, and config.sub to test source tree.
7105 Drop AC_CONFIG_AUX_DIR setting.
7106 (AT_CHECK_CONFIGURE): Drop setting of `top_srcdir'.
7107 * tests/torture.at (Substitute a 2000-byte string): Drop
7108 AC_CONFIG_AUX_DIR setting, copy install-sh to test source tree.
7109 (Substitute a newline, datarootdir workaround): Likewise.
7110 (Define a newline): Adjust for linenumber changes in configure.ac.
7111 * tests/foreign.at (Libtool): Adjust comment to reflect changes.
7113 * tests/semantics.at (AC_PATH_PROGS_FEATURE_CHECK): Skip test
7114 if `pwd` contains whitespace.
7116 Quote $abs_top_srcdir in tests.
7117 * tests/local.at (AT_CHECK_PERL_SYNTAX): Likewise.
7118 * tests/tools.at (Syntax of the shell scripts): Likewise.
7120 * tests/m4sh.at (LINENO): Quote $0.
7122 Fix testsuite program wrapper for whitespace in `pwd`.
7123 The problem here is that the usual mantra is that command
7124 variables can contain arguments, thus we cannot just escape
7125 $AUTOCONF, $AUTOM4TE etc. The compromise is to put the
7126 $top_builddir/tests directory early in $PATH, so that the
7127 wrappers are found by their plain name.
7128 * tests/wrapper.as: Put $testdir early in $PATH.
7129 (AUTOCONF, AUTOHEADER, AUTOM4TE): Set to plain command names.
7131 Proper config.status --file/--header and $srcdir escaping.
7132 * lib/autoconf/status.m4 (_AC_OUTPUT_MAIN_LOOP): Quote special
7133 characters in $ac_file_inputs.
7134 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER): eval $ac_file_inputs
7136 * tests/torture.at (datarootdir workaround): Adjust.
7137 (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS): Extend test.
7139 Fix Autotest for whitespace in `pwd`.
7140 * lib/autotest/general.m4 (AT_INIT)
7141 <at_func_create_debugging_script, Driver Loop>:
7142 Quote $at_group_dir.
7143 * tests/autotest.at (whitespace in absolute testdir): New test.
7145 * lib/autom4te.in: Quote @datadir@.
7147 Proper file name escaping in Autoconf programs and Perl modules.
7148 This includes escaping of characters special to the shell
7149 as well as special to Perl, e.g., leading `<' or `>'.
7150 For example, when $file starts with `>', `open ">$file"'
7151 wrongly tries to append to a different file.
7152 * bin/autoconf.as: Fix quoting for autom4te options.
7153 * lib/Autom4te/General.pm (shell_quote): New function, taken
7154 from coreutils, written by Jim Meyering.
7156 * bin/autom4te.in (files_to_options, handle_m4): Use shell_quote
7158 * bin/autoreconf.in (parse_args): Likewise.
7159 * bin/autoscan.in (main): Likewise.
7160 * bin/autoupdate.in (main): Likewise.
7161 * bin/autoheader.in: Likewise, fixing old insufficient escaping.
7162 * bin/ifnames.in: Likewise, XFile usage fixes.
7163 * tests/tools.at (autom4te and whitespace in file names): Extend
7164 test. Test twice, with special characters allowed on w32, and the
7165 rest. Test leading and trailing whitespace, for `open_quote'.
7166 (autotools and whitespace in file names): New, analogous test.
7167 Reported by Paul Eggert and Benoit Sigoure, additional suggestions
7168 by Russ Allbery and Eric Blake.
7171 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm,
7172 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Likewise.
7173 * lib/Autom4te/FileUtils.pm (open_quote): New function.
7174 (update_file, contents): Use it.
7176 * Makefile.am (autom4te-update): Rewrite for git.
7178 2007-12-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7180 * doc/autoconf.texi (autom4te Invocation, Autom4te Cache): Fix typos.
7182 Fix copyright years.
7183 * Makefile.am, doc/install.texi, lib/autoconf/fortran.m4,
7184 lib/autoconf/lang.m4, lib/freeze.mk: Likewise.
7186 2007-12-04 Eric Blake <ebb9@byu.net>
7188 Manually resync with gnulib, since 'make cvs-update' no longer works.
7189 * build-aux/config.guess: New upstream version.

7192 When using older automake, don't downgrade build-aux/texinfo.tex.
7193 * configure.ac (AM_INIT_AUTOMAKE): Add no-texinfo.tex option.
7194 * doc/Makefile.am (TEXINFO_TEX): Add.
7196 2007-11-27 Paul Eggert <eggert@cs.ucla.edu>
7198 Fix AC_C_BIGENDIAN bug caused by new awk method of substitution.
7199 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Don't comment out the
7200 #undef as this runs afoul of our new way of creating config.h.
7201 Problem reported by Jim Meyering in
7202 <http://lists.gnu.org/archive/html/autoconf-patches/2007-11/msg00164.html>.
7204 2007-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7206 Fix autom4te for unusual characters in input file names.
7207 * bin/autom4te.in (files_to_options): Quote active characters
7209 * tests/tools.at (autom4te and white space in file names):
7212 * doc/autoconf.texi (Limitations of Usual Tools) <awk>:
7213 Document that Tru64 awk always splits $0.
7215 2007-11-24 Stepan Kasal <kasal@ucw.cz>
7217 * lib/autotest/general.m4 (AT_INIT): Do not extract the
7218 `#AT_STOP_...' line at the end of each test.
7220 2007-11-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7222 * lib/autotest/general.m4 (AT_INIT): For awk line number
7223 extraction script, ensure `$at_group' has a defined value
7224 even for the empty set, and properly quote its usage inside
7227 2007-11-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7229 * doc/autoconf.texi (Shell Functions): New chapter. Document
7230 IRIX sh $0 issue in functions, move content from ...
7231 (Portable Shell): ... here.
7232 (Shell Script Compiler): Note that shell functions are not
7233 totally unportable any more.
7235 2007-11-22 Stepan Kasal <kasal@ucw.cz>
7236 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7238 * lib/autotest/general.m4 (AT_INIT): Exit awk script after
7239 extracting the line numbers of the last needed test.
7241 2007-11-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7243 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7246 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7248 Fix IRIX testsuite debugging failures: $0 in functions.
7249 * lib/autotest/general.m4 (AT_INIT) <at_func_create_debugging_script>:
7250 Do not use $0 inside a function, as IRIX sh will set that to the
7251 function name rather than the script invocation name.
7253 2007-11-19 Paolo Bonzini <bonzini@gnu.org>
7254 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7256 * lib/autotest/general.m4 (at_func_test): Use cached line numbers
7257 to extract test scripts.
7258 (AT_INIT): Extract and cache test script line numbers.
7260 2007-11-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7262 * lib/autotest/general.m4: Revert 2007-11-15 patch and
7263 subsequent fixups; the awk -> here-document conversion trashes
7264 performance too much with AIX sh.
7266 2007-11-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7268 * tests/local.at: Do not test m4, perl with AT_TESTED.
7270 Diagnose and guard against write errors dealing with config.status.
7271 The general idea is this: all write failures from `configure'
7272 writing `config.status' are indicated by $ac_write_error, which
7273 is only checked at the end. This is safe because config.status
7274 code is not executed before the file is complete. Other write
7275 failures, be they inside config.status, or in sub shell/awk
7276 scripts spawned from configure or config.status, typically need
7277 earlier checking, as their results are used right afterwards.
7278 * lib/autoconf/status.m4 (AC_OUTPUT): Initialize `ac_write_fail'
7279 before writing config.status, check afterwards.
7280 (_AC_OUTPUT_FILES_PREPARE, _AC_OUTPUT_FILE)
7281 (_AC_OUTPUT_HEADERS_PREPARE,_AC_OUTPUT_CONFIG_STATUS):
7282 Set `ac_write_error' for write failures to config.status. Barf
7283 upon write failures to temporary files.
7284 Adjust note about closing and reopening the here-document.
7285 (_AC_OUTPUT_HEADER, _AC_OUTPUT_LINK, _AC_OUTPUT_COMMAND)
7286 (_AC_OUTPUT_MAIN_LOOP): Likewise, adjust note about closing and
7287 reopening the here-document.
7288 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7289 Ensure `ac_write_error' does not escape into config.status.
7290 Also, add a couple of code paths not yet exercised in the test
7291 suite: a config file with input from stdin, and a config header
7293 Suggestion for catching write errors by Bruno Haible.
7295 2007-11-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7297 Avoid error with Tru64 awk and testsuite lines with many words.
7298 * lib/autotest/general.m4 (AT_INIT): In the awk script that
7299 reads the testsuite, set the field separator to an unusual value,
7300 in order to not run over the limit of 199 fields. Tru64 4.0D awk
7301 even splits the input if $i, i>0, was never accessed in the script.
7303 Revert 2007-10-17 change.
7304 * TODO: Multiline args in config files and headers mean something
7305 different and are not fixed, see
7306 <http://lists.gnu.org/archive/html/autoconf-patches/2007-05/msg00017.html>
7307 Report by Stepan Kasal.
7309 * doc/autoconf.texi (Generic Programs): Fix typo.
7311 2007-11-16 Stepan Kasal <kasal@ucw.cz>
7313 AC_*_TOOL does not canonicalize the prefix
7314 * doc/autoconf.texi (Generic Programs): Do not say that
7315 the *_TOOL macros canonicalize, they simply use the `host_alias'.
7317 2007-11-16 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7319 Diagnose write errors in config.status instantiations.
7320 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE)
7321 (_AC_OUTPUT_HEADER, _AC_OUTPUT_MAIN_LOOP): Bail out
7323 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
7324 Extend test to also check for some write error failures, using...
7325 <AT_CHECK_CONFIG_CREATION_NOWRITE>: ...this new macro.
7326 Report by Bruno Haible.
7329 * lib/autotest/general.m4 (AT_INIT) <at_func_log_failure>: Fix

7339 2007-11-15 Paolo Bonzini <bonzini@gnu.org>
7340 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7342 * lib/autotest/general.m4 (at_func_test): Remove.
7343 (AT_INIT): Pre-extract test groups into separate files.
7344 (AT_CLEANUP): Source pre-extracted file instead of calling at_func_test.
7345 Remove at-test-source files together with the $at_group_dir.

7354 2007-11-14 Paul Eggert <eggert@cs.ucla.edu>
7356 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Make comment match
7359 2007-11-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7361 * lib/autoconf/status.m4: Fix a couple of comment typos.
7363 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Use $as_me, not $me.
7365 2007-11-13 Jim Meyering <meyering@redhat.com>
7367 Clean up the rule to create "expr".
7368 * tests/Makefile.am (expr): Don't redirect directly to target.
7369 Redirect just once, not for each echo statement.
7370 Use $@, not literal "expr".
7372 2007-11-13 Paul Eggert <eggert@cs.ucla.edu>
7374 Don't worry about preprocessor when testing long long.
7375 See: http://lists.gnu.org/archive/html/bug-gnulib/2007-11/msg00075.html
7376 * doc/autoconf.texi (Preprocessor Arithmetic): New section.
7377 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT):
7378 These no longer check for preprocessor flaws.
7379 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET):
7380 Do not check for preprocessor flaws.
7382 2007-11-13 Jim Meyering <meyering@redhat.com>
7384 Adapt dependencies, now that a version change doesn't modify configure.ac
7385 * GNUmakefile: Remove "make clean" kludge.
7386 * lib/m4sugar/Makefile.am (version.m4): Depend on Makefile, not
7388 Don't redirect directly to target.
7389 Use $@, not literal "version.m4".
7391 2007-11-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7393 * doc/autoconf.texi (Making testsuite Scripts): Document
7394 ":;{" shorthand as in previous patch.

7403 * tests/Makefile.am ($(srcdir)/package.m4): Likewise.
7405 2007-11-12 Jim Meyering <meyering@redhat.com>
7407 Add more non-srcdir build support.
7408 * GNUmakefile (dummy): Split a long line.
7409 Add -v option to autoreconf invocation.
7411 Remove the autoreconf-provided INSTALL, so that we regenerate it.
7412 * GNUmakefile (dummy): Remove INSTALL.
7414 Remove racy commands to build scripts in bin/ and tests/.
7415 * man/Makefile.am (.x.1): Now that scripts in bin/ and tests/
7416 are guaranteed to be built, remove the rules that tried to build
7417 them. Before, with a parallel build, these rules could lead to
7418 two processes writing tests/wrapper.in concurrently.
7420 Build in man/ only *after* building in bin/ and tests/.
7421 * Makefile.am (SUBDIRS): The man-page-creation process runs $(MAKE)
7422 in both bin/ and tests/.
7424 Accommodate non-srcdir build-from-checkout.
7425 * build-aux/git-version-gen: Require an additional parameter: $srcdir.
7426 Use git's --git-dir=$srcdir/.git option.
7427 Add quotes, in case tarball_version_file contains shell meta-characters.
7428 * GNUmakefile (_curr-ver): Pass $(srcdir) to git-version-gen.
7429 * configure.ac: Pass "." to git-version-gen.
7431 Avoid spurious test failures due to version skew.
7432 * GNUmakefile (dummy): Run $(MAKE) clean after autoreconf -i.

7464 writable again for the `stderr' file, and ignore errors due to
7465 the attempt to write configure.lineno.

7471 * tests/Makefile.am (package.m4): Adjust target.
7472 Don't redirect directly to $@.
7473 (CLEANFILES): Add package.m4.
7474 ($(TESTSUITE)): Depend on just-built package.m4, not the one
7476 When running $(AUTOTEST), search "." before searching $(srcdir).
7478 Avoid a race condition that would make parallel "distclean" fail.
7479 * tests/Makefile.am (distclean-generic): Replace the default,
7480 automake-provided rule with an identical one, but with an additional
7481 dependency on distclean-local. Simply adding the dependency would
7482 cause automake not to emit the rule at all.
7483 * BUGS: Building with -jN works, now.
7485 Distribute git-version-gen.
7486 * Makefile.am (EXTRA_DIST): Add build-aux/git-version-gen,
7487 since GNUmakefile is distributed, and requires it for dist* rules.
7489 Remove two more generated files from version control.
7490 * INSTALL: Remove generated file.
7491 * lib/autoscan/autoscan.list: Remove generated file.
7493 2007-11-09 Paul Eggert <eggert@cs.ucla.edu>
7495 * GNUmakefile (PATH): Remove stray apostrophes; they become
7496 part of PATH, which isn't wanted here.
7498 2007-11-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7500 New config files output variable `top_build_prefix'.
7501 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Substitute
7503 * doc/autoconf.texi (Preset Output Variables): Document it.
7505 Report by Bob Friesenhahn.
7507 Avoid expr for arithmetic evaluation if the shell accepts $((...)).
7508 * lib/autotest/general.m4 (AT_INIT) <at_func_arith>: New
7509 function, to parametrize arithmetic with expr vs. the shell.
7510 Use it where possible.
7511 Suggestion by Benoit Sigoure.
7513 2007-11-03 Benoit Sigoure <tsuna@lrde.epita.fr>
7515 Adjust the documentation of autotest WRT atlocal.
7516 * doc/autoconf.texi (Making testsuite Scripts): It is not necessary,
7517 when using Automake, to write a rule to produce atlocal, since it's
7518 an AC_CONFIG_FILES. Mention that atlocal.in needs to be
7519 distributed, not atconfig.in.
7521 2007-11-04 Eric Blake <ebb9@byu.net>
7523 Update list information.
7524 * README: Mention new autoconf-commit list.
7525 * doc/autoconf.texi (Introduction): Mention autoconf-commit list.
7527 2007-11-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7529 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Fix comment typo.
7531 * lib/m4sugar/Makefile.am (version.m4): Another bash bug workaround.
7533 * build-aux/.gitignore: Ignore mkinstalldirs.
7535 * doc/autoconf.texi (autoreconf Invocation): Fix an underfull line.
7537 2007-11-03 Jim Meyering <meyering@redhat.com>
7539 s/-/./ in snapshot version string: 2.61a-256-8b556 -> 2.61a.256-8b556
7540 * build-aux/git-version-gen: This syncs from coreutils.
7542 Adjust the build procedure so "make check" works reliably.
7543 * README-hacking: Include an extra step between "make" and
7544 "make check" to ensure that the latter passes.
7546 Use just-built tools, when possible.
7547 * GNUmakefile (PATH): Set and export here, ...
7548 (dummy): ... rather than here.
7550 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7551 and Andreas Schwab <schwab@suse.de>
7553 * tests/Makefile.am ($(srcdir)/package.m4): Work around bash
7556 2007-11-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7558 * configure.ac (AC_PREREQ): Require version 2.60, for
7559 AC_PROG_SED, AC_PROG_GREP.
7561 2007-11-02 Benoit Sigoure <tsuna@lrde.epita.fr>
7562 and Jim Meyering <meyering@redhat.com>
7563 and Andreas Schwab <schwab@suse.de>
7564 and Eric Blake <ebb9@byu.net>
7566 Document a bug in GNU Bash with compound commands and redirections.
7567 * doc/autoconf.texi (Limitations of Builtins): Mention that GNU
7568 Bash doesn't properly set $? when `{ ... } >/bad' fails, and give
7571 2007-11-03 Eric Blake <ebb9@byu.net>
7573 Support m4 1.4.5 in testsuite.
7574 * tests/torture.at (Define a newline): Exclude line numbers in
7576 Reported by Ralf Wildenhues.
7578 2007-11-03 Jim Meyering <meyering@redhat.com>
7580 Remove automake-provided files from version control.
7581 * build-aux/elisp-comp: Remove file.
7582 * build-aux/install-sh: Remove file.
7583 * build-aux/missing: Remove file.
7584 * build-aux/mdate-sh: Remove file.
7585 * build-aux/.gitignore: New file.
7586 Suggestion from Ralf Wildenhues.
7588 2007-11-03 Eric Blake <ebb9@byu.net>
7590 Adjust version comparison to account for git snapshot numbers.
7591 * lib/m4sugar/m4sugar.m4 (_m4_version_unletter): Also treat - as a
7592 component separator.
7593 * doc/autoconf.texi (Number processing Macros)
7594 <m4_version_compare>: Document this change.
7595 * tests/m4sugar.at (m4@&t@_version_compare): Test it.
7597 2007-10-30 Bruno Haible <bruno@clisp.org>
7599 * lib/autoconf/types.m4 (_AC_TYPE_LONG_LONG_SNIPPET): New macro,
7600 extracted from AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT.
7601 (AC_TYPE_LONG_LONG_INT, AC_TYPE_UNSIGNED_LONG_LONG_INT): Use it.
7602 Fixes problem with Sun C 5.[0-8] in 32-bit mode, reported in
7603 <http://lists.gnu.org/archive/html/autoconf-patches/2007-10/msg00210.html>
7604 Suggested by Paul Eggert.
7606 2007-10-28 Jim Meyering <meyering@redhat.com>
7608 * README-hacking: Autoconf, Automake, and Perl are required to build.
7609 List Gzip and Tar separately. Suggested by Ralf Wildenhues.
7611 2007-10-28 Jim Meyering <meyering@redhat.com>
7613 README-hacking: Recommend running autoreconf -vi.
7614 * GNUmakefile (dummy): Use autoreconf -i, with appropriate PATH,
7615 so that we use just-built tools when they're available.
7616 Suggestions from Ralf Wildenhues.
7618 2007-10-28 Jim Meyering <meyering@redhat.com>
7620 Make inter-release --version output more useful.
7622 Now, each unofficial build has a version "number" like 2.61a-19-58dd,
7623 which indicates that it is built using the 19th change set
7624 (in _some_ repository) following the "v2.61a" tag, and that 58dd
7625 is a prefix of the commit SHA1.
7626 * build-aux/git-version-gen: New file.
7627 * configure.ac: Run it to set the version.
7628 (AM_INIT_AUTOMAKE): Don't check NEWS here.
7629 * Makefile.am (dist-hook): Arrange so that .version appears only
7630 in distribution tarballs, never in a checked-out repository.
7631 * .gitignore: Add .version here, too. Just in case.
7632 * tests/Makefile.am ($(srcdir)/package.m4): Depend on Makefile,
7633 not configure.ac, now that the version number changes automatically.
7635 Ensure that $(VERSION) is up to date for dist-related targets.
7636 * GNUmakefile: Arrange to rerun autoconf, if the version reported by
7637 git-version-gen doesn't match $(VERSION), but only for dist targets.
7639 2007-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
7641 Fix `Deep Package' failure with a configure script early in PATH
7642 * tests/torture.at (Deep Package): Add `.' early in PATH.
7643 Report by Jim Meyering.

7668 and Eric Blake <ebb9@byu.net>
7670 * lib/autoconf/c.m4 (AC_C_RESTRICT): Work around Sun C++ compatibility
7671 problem reported by Bruno Haible in
7672 <http://lists.gnu.org/archive/html/bug-autoconf/2007-10/msg00027.html>.
7674 2007-10-22 Eric Blake <ebb9@byu.net>
7676 * doc/autoconf.texi (Particular Types): Mention bug in HP-UX 11.00
7679 2007-10-22 Paul Eggert <eggert@cs.ucla.edu>
7681 Don't check for bug in HP-UX 11.00 cpp.
7682 * lib/autoconf/types.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT):
7683 Use -1ull rather than -1u, since that causes problems with gnulib; see
7684 <http://lists.gnu.org/archive/html/bug-gnulib/2007-10/msg00329.html>.

7702 escaping of backslash in here-documents.
7704 Fix `Deep Package' test failure on FreeBSD.
7705 * tests/torture.at (Deep Package): Do not add `.' to $PATH
7706 unnecessarily. Do not try running `/bin/sh configure' with a
7707 configure script to be found in $PATH, if the shell does not do
7708 this resolution. Fixes test failure on FreeBSD.
7710 Fix config header generation with AIX awk.
7711 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS_PREPARE): In awk
7712 script, use helper array D_is_set, as `" 0"' does not evaluate
7713 to true for AIX awk.

7754 array of banner text from a special diversion.
7755 <PARSE_ARGS_END>: No longer need awk to find banners.
7756 <TESTS>: Banners are no longer processed by main driver loop, so
7757 we no longer need case statement.

7856 use $as_myself, not $0.

8934 Document the restrictions on AC_CHECK_ALIGNOF's type argument.
8935 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW):
8936 For C, just try sizeof (TYPE) and sizeof ((TYPE)); if the former
8937 works but the latter doesn't, then it's a valid type.
8938 This lets people use function types and so forth.
8939 For C++ there doesn't seem to be a simple solution, so leave it alone.
8940 (AC_CHECK_SIZEOF): Allow argument to be a variable.
8941 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Don't bother to invoke

9137 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9139 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
9140 early on the reader side, drop stderr of the input to avoid
9141 `broken pipe' error output; this may happen even with shell
9142 builtin `echo' of some bash versions. Reports by Ian Macdonald
9143 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
9145 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

9158 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
9159 * doc/autoconf.texi (Signed Overflow Examples): Give more
9160 discussion about the allow_superuser_privileges example,
9161 and change it a bit to make things clearer.
9162 (Optimization and Wraparound): Clarify whether the compiler
9163 will generate an infinite loop for the example derived from
9164 Autoconf's mktime test.
9165 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
9166 Also, clarify unsigned multiplication overflow.
9168 2007-01-04 Eric Blake <ebb9@byu.net>
9170 * bin/Makefile.am (RELEASE_YEAR): New macro.
9171 (edit): Use it to supply correct copyright year to scripts.
9172 * bin/autoconf.as (version): Use it.
9173 * bin/autoheader.in ($version): Likewise.
9174 * bin/autom4te.in ($version): Likewise.
9175 * bin/autoreconf.in ($version): Likewise.
9176 * bin/autoscan.in ($version): Likewise.

9180 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
9182 * doc/autoconf.texi (Integer Overflow): Revised based on today's
9183 feedback. The most important changes document what happens when
9184 you convert an out-of-range value to a signed integer type, and
9185 say that (sum < a) != (b < 0) reliably detects overflow when sum =
9188 * doc/autoconf.texi (Integer Overflow): Greatly expand and
9189 rewrite, taking notions from the recent discussion on the gcc and
9190 autoconf mailing lists; please see
9191 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
9192 and follow the many links.
9193 (Integer Overflow Basics, Signed Overflow Examples):
9194 (Optimization and Wraparound, Signed Overflow Advice):
9195 (Signed Integer Division): New sections.
9197 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
9199 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
9200 preprocessor macro arguments in traced name.
9201 * doc/autoconf.texi (Defining symbols): Document longstanding
9202 support for AC_DEFINE-ing macros with arguments, and document
9203 behavior when the same variable has multiple AC_DEFINEs.
9204 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
9205 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
9206 macros directly, giving much shorter and simpler code.
9208 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
9210 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
9211 space before "$ac_configure_args" to prevent a 'config.status
9212 --recheck' failure if ac_configure_args doesn't contain a leading
9213 space. This works around a problem with the XEmacs configure.ac,
9214 which uses the (undocumented) ac_configure_args variable
9215 inconsistently with Autoconf.
9217 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
9219 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
9220 Include <limits.h>, and use its INT_MAX to rewrite the
9221 j loop so that it does not overflow 'int'. Problem reported by
9223 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
9224 Play it safe by shifting left by 1 rather than multiplying by 2,
9225 as GCC is less likely to optimize this away when the value
9226 is signed (when it assumes overflow leads to undefined behavior).
9227 Also, don't assume time_t uses two's complement.
9229 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9231 * tests/torture.at (Substitute a 2000-byte string): Avoid using
9232 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
9233 dumps core on it. Report by Tim Rice.
9235 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9237 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
9238 --disable-option-checking to --help output even when
9239 AC_PRESERVE_HELP_ORDER is not used.
9240 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
9241 --with argument, rather than argument with [-.] replaced by
9243 * NEWS: Fix typo in previous change; the news was in the
9246 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
9248 * NEWS: Warnings are now generated by default for unknown
9249 --enable-* and --with-* options.
9250 * doc/autoconf.texi (Option Checking): Renamed from
9251 (Configure Option Checking). Tighten up the wording a bit.
9252 (External Software, Package Options): Cross-reference to Option
9253 Checking, and use this to shorten our section.
9254 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
9255 "$x" to test "x$foo" != x.
9256 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
9257 Don't warn if $enable_option_checking is "no".
9258 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
9259 ac_unrecognized_opts to the empty string.
9260 Don't echo the unrecognized opts, as this might mishandle
9261 backslashes or leading -.
9262 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
9263 usage next to the other --disable-FEATURE options in the
9266 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
9268 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
9269 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
9270 Print warning for unrecognized --with and --enable options
9271 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
9272 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
9273 Disable option checking when subdirs are configured.
9274 (AC_OUTPUT): If warnings are enabled, print warning about
9275 unrecognized --with and --enable options at the end of
9276 the configure output (as well as at the beginning).
9277 * doc/autoconf.texi (Option Checking): New node.
9278 Document new option warning functionality.
9280 2006-12-16 Eric Blake <ebb9@byu.net>
9282 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
9283 * NEWS: Start news for current version.
9285 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
9287 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
9288 Define HAVE_GETMNTENT to 1, not to the empty string.
9289 Problem originally reported by Jochen Friedrich in
9290 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
9292 This change prompted by a problem report by Andrey Simonenko in
9293 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
9294 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
9295 object-like macros only, in the traditional portable character
9297 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
9298 Warn about attempts to define things that are not identifiers.
9299 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
9300 awful hack that AC_DEFINEd macro names containing parentheses.
9302 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
9304 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
9305 too drastic, even if Texinfo in theory requires it for info mode.
9307 (config.status Invocation): Renamed back from Recreating a
9309 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
9310 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
9312 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9314 * NEWS: Version 2.61a.
9316 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
9317 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9319 * NEWS: Document changes with echo and printf, and the lack
9320 of limits on the total size of multi-line values of substituted
9321 variables, and the AC_FUNC_FSEEKO fix.
9323 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
9325 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
9326 Writing configure.ac.
9327 (Autoconf Input Layout): Renamed from configure.ac Layout.
9328 (Recreating a Configuration): Renamed from config.status Invocation.
9329 (Obsolete Recreation): Renamed from Obsolete config.status Use.
9330 (acconfig Header): Renamed from acconfig.h.
9331 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
9332 (Writing Testsuites): Renamed from Writing testsuite.at.
9333 (Autom4te Cache): Renamed from autom4te.cache.
9335 * BUGS: Remove mention of VPATH problem, since it's now documented
9336 not to be a bug in the Autoconf build procedure itself, but rather
9337 a problem with the proprietary `make' programs.
9339 * doc/autoconf.texi (Build Directories): Add a cross reference
9342 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
9343 * doc/standards.texi: Sync from gnulib.
9345 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
9346 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
9347 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
9348 generated automatically.
9350 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
9352 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
9353 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
9354 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
9356 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9358 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
9359 `CEOF$ac_eof' special marker, the awk script cannot contain a
9360 line matching `^CEOF', so this is not needed any more.
9361 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
9362 special marker in the test.
9364 2006-12-06 Stepan Kasal <kasal@ucw.cz>
9366 * tests/tools.at (autom4te preselections): Use `find -newer';
9367 remove one of the sleeps.
9369 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
9370 more readable, using ...
9371 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
9373 * doc/autoconf.texi (autoheader Invocation): Do not double-
9374 quote the parameter of `AH_BOTTOM' in the example.
9376 2006-12-05 Stepan Kasal <kasal@ucw.cz>
9378 * doc/autoconf.texi (Configuration Headers): Remove the
9379 example with multiple input files.
9380 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
9381 multiple input files.
9383 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9385 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
9386 creating the awk substitution script, handle one input line at a
9387 time, so that the maximum length of a substituted (multi-line)
9388 value is not limited by the size of the sed pattern space.
9389 The trade-off is a slightly repetitive sed script.
9390 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
9391 can only have up to 7 characters, due to Solaris 10 /bin/sed.
9392 * tests/torture.at (Substitute a 2000-byte string): Increase the
9393 test with several long lines, they should not be caught by sed
9396 * tests/tools.at (autom4te preselections): New test, to flag
9397 entries missing from autom4te.cfg.
9398 Report by David Byron <dbyron@hheld.com>.
9400 * tests/torture.at (Substitute a 2000-byte string): Actually use
9401 AC_PROG_AWK, so the last change works as intended.
9402 (Substitute and define special characters): Likewise.
9403 (Substitute a newline): Likewise.
9405 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
9406 instead of `awk' consistently.
9407 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
9408 * tests/torture.at (Torturing config.status): Test both the
9409 result of AC_PROG_AWK and plain awk.
9410 (Substitute a 2000-byte string): Likewise.
9411 (Substitute and define special characters): Likewise.
9412 (Substitute a newline): Likewise.
9414 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
9416 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
9417 can be assigned to a function pointer. Problem reported by
9418 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
9419 part of a patch by Ralf Wildenhues in that same bug report.
9421 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
9423 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
9424 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
9426 2006-12-01 Eric Blake <ebb9@byu.net>
9428 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9429 cross-compiling from cygwin to mingw.
9430 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
9431 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
9432 to lib/autoconf/c.m4.
9434 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9436 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
9437 string for more reliable failure. Wrap the entire test that
9438 causes the broken Solaris printf to dump core, in a subshell,
9439 so the segmentation fault message is reliably suppressed.
9440 Fix shell expansion errors by using /usr/ucb/echo always;
9441 avoid an error on systems without it by another subshell.
9442 Avoid m4 expansion of `$1'. Set the zeroth argument of the
9443 subshell-$as_echo to `as_echo', for better error message.
9445 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9447 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
9448 `BASH_SOURCE' contain a newline, set them to empty, as they may
9451 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
9453 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
9454 years and is too hard to maintain now. The last straw was
9455 reported by Jerker Baeck in
9456 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
9457 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
9458 * doc/autoconf.texi (Particular Functions): Move
9459 AC_FUNC_SETVBUF_REVERSED from here...
9460 (Obsolete Macros): ... to here. Say that it does nothing now.
9461 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9462 Turn into (almost) a no-op.
9464 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
9466 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
9467 These macros are obsolescent and new applications shouldn't need them.

9478 @VAR1@VAR2 has unspecified behavior. Problem reported by
9480 * NEWS: Mention this.
9482 * Makefile.am: Put only a single '#' into the copyright notice,
9483 so that it's also present in the output file. Standardize wording
9484 in makefile copyright notices to match GNU coding standards.

9498 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9500 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
9501 in the sed script that mangles the awk script: delete up to the
9502 first exclamation mark only.
9503 * tests/torture.at (Substitute and define special characters):
9506 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9508 Rewrite config files generation: avoid quadratic growth in
9509 the number of substituted variables by using awk instead of sed
9510 for the bulk of the substitutions.
9511 * NEWS: Mention this.
9512 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
9513 forbidden in the output (and thus input) file.
9514 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
9515 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
9516 generate just one large awk script for substitutions,
9517 eliminating much of the earlier complexity, while adding some
9518 new complexity. Only expand the substitution templates at
9519 configure time, for smaller configure script size. If
9520 _AC_SUBST_FILES are used, test 'awk' for working getline support
9521 at config.status time. If absent, interpolate through the
9522 shell. The awk script was written with much help
9523 from Paolo Bonzini and Paul Eggert.
9524 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
9525 (_AC_SED_FRAG_NUM): Likewise.

9528 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
9529 * tests/torture.at (Substitute a 2000-byte string): Also
9530 substitute a line with 1000 words, and a variable with several
9532 (Substitute and define special characters): Test awk special
9533 characters, and put substitution input strings `@foo@' in the
9534 output, to test that no recursion happens; test several other
9535 combinations from Paolo Bonzini.
9537 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
9539 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
9540 that replaced echo with AS_ECHO where this wasn't necessary.
9541 Problem reportd by Ralf Wildenhues.
9542 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
9543 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
9544 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
9546 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
9548 * lib/freeze.mk (GREP): Removed, no need to initialize this.
9550 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
9552 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
9553 that traditional Awk lacks 3-arg "split". It has it.
9554 Mention that FS must be a single character, and a few other
9555 99-byte limits of traditional Awk.
9556 Mention that if (i in a) doesn't work with traditional Awk.

9562 (Newline-CODE-BS-newline in command):
9563 (Single-quote-BS-newline in command):
9564 (Single-quote-newline-BS-newline in command):
9565 Use printf '%s\n' instead of echo, for portability to hosts
9566 where echo interprets backslashes. This will break on hosts
9567 that lack printf, but for now let's assume all such hosts
9568 are dead (if not, we should get reports of test failures).
9570 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9572 'echo' has some portability problems, when given a first argument
9573 with a leading '-', or when given any argument containing '\'.
9574 Avoid using 'echo' in these cases.
9575 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.

9603 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
9604 Don't use ECHO_T, since ECHO_N is now reliable.
9605 * lib/autotest/general.m4 (AT_INIT): Likewise.
9606 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
9607 rather than using a here-document to put the script into a file.
9608 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
9610 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
9611 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
9612 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
9613 bug, but we might as well stop using ECHO_N and ECHO_C internally.

9616 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

9618 operand, as AS_ECHO requires. Avoid double file name expansion.
9619 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
9620 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
9621 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
9622 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
9623 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
9624 Double-quote strings that would otherwise contain M4 comments.
9625 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
9627 * configure.ac (AC_INIT): Bump to 2.61a.
9630 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
9634 * configure.ac (AC_INIT): Bump to 2.61.
9637 * tests/autotest.at (Macro with backslash in a test title):
9638 Comment out for now, as this tests neither fails nor passes
9639 reliably. Problem reported by Ralf Wildenhues.
9641 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
9643 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
9644 in previous change, which caused test failures.

9754 and Stepan Kasal <kasal@ucw.cz>
9756 Handle special characters in test case titles correctly.
9757 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
9759 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
9760 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
9761 argument. Extend to check titles printed by ./micro-suite and
9762 ./micro-suite -l and the title in micro-suite.log.
9763 (Backquote in a test title,
9764 Single-quote in a test title,
9765 Double-quote in a test title): Don't expect failure anymore.
9766 (Backslash in a test title): Put a non-whitespace character after the
9767 backslash so that Bourne shells might actually see it as an escape
9769 (Brackets in a test title,
9770 Pound in a test title,
9771 Comma in a test title,

9787 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
9789 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
9790 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
9791 5363) simply issues a warning when dividing by zero at compile
9792 time. Problem reported by Elias Pipping.
9794 2006-10-26 Eric Blake <ebb9@byu.net>
9797 * doc/autoconf.texi (Evaluation Macros): Improve the example to
9798 show effect on macros that expand with commas.

9825 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
9826 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
9827 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
9828 reported by Nelson H. F. Beebe for Coreutils 6.4.
9830 * tests/tools.at (autoconf --trace: user macros): Remove test
9831 for tracing multiline macros, since m4 1.4.7a uses a different
9832 way to number lines. Problem reported by Ralf Wildenhues.
9834 2006-10-24 Stepan Kasal <kasal@ucw.cz>

9910 (Imported from Automake.)
9911 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
9912 which incorrectly sets the mode of an existing destination
9913 directory. In some cases the unpatched install-sh could do the
9914 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
9915 system. We hope this is rare in practice, but it's clearly worth
9916 fixing. Problem reported by Alex Unleashed in
9917 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
9918 Also, don't bother to check for -m bugs unless we're using -m;
9919 suggested by Stepan Kasal.

9998 Use a better substitute, by inspecting the output of "ls"
9999 rather than just using ":".
10000 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
10001 rather than AS_EXECUTABLE_P, since we needn't worry about
10002 non-regular files here.
10004 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
10005 due to configuration hassles with this. See Tonya Underwood's report

10029 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
10030 comment about ac_cpp_err; it was incorrect, and anyway
10031 ac_cpp_err is being removed below.
10032 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
10033 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
10034 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
10036 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
10037 with werror_flag and conftest.err and so forth. This is more
10038 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
10039 and anyway the user shouldn't normally want to see this gorp logged.
10040 Problem reported by Ralf Wildenhues.
10041 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
10042 empty, not 'no', since the rest of the code uses 'test -z'.
10044 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
10046 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10047 Use a single call to AC_DO_TOKENS rather than multiple, for
10049 (_AC_LINK_IFELSE): Test that resulting file is executable.
10050 Problem reported by mwoehlke in
10051 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
10053 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
10054 than creating a file to use with test -x; this is much faster.
10056 2006-10-02 Bruno Haible <bruno@clisp.org>
10058 * lib/autom4te.in (Automake-preselections): Add

10068 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the

10070 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
10071 Set cache var to 'unknown' (not 'no') if leaving the macro unset
10072 still doesn't let the program compile.
10073 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
10076 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
10077 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
10078 include it, without including anything else.
10079 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
10081 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

10517 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.

10540 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10542 * doc/autoconf.texi: Fix some typos.
10544 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
10546 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10547 more globally, since the 2006-06-30 patch didn't suffice. Problem
10548 reported by Keith Marshall. Also, don't bother with builddir2,
10549 since it shouldn't be needed any more.
10551 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
10553 * doc/autoconf.texi (Generic compiler characteristics):

10570 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
10572 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
10573 Require that long long int be at least 64 bits wide. C99 requires
10574 this and enough programs depend on it so we should check for it.
10575 Bruno Haible reports in
10576 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
10577 that long long int is 32 bits wide with some nonstandard compilers.

10582 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
10583 to a nonexistent file, so that we don't have to worry about
10584 a local site configuration that doesn't use /usr/local.
10585 Problem reported by Keith Marshall in
10586 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
10588 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
10590 * doc/autoconf.texi: Be more consistent about using @acronym with
10591 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
10592 quite right (it talked about "OSF/Tru64", even though the
10593 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
10594 and it even mentioned "OSF 4"!) and at this point there's little
10595 reason to talk about OSF any more, since it died in 1994.
10596 (Specific Compiler Characteristics): Simplify example of
10597 negative-size array.
10598 (File Descriptors): Reorder to make the text flow better.
10599 Remove joke about "appreciate the various levels"; I didn't get it.

10601 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
10602 (File Descriptors, Limitations of Usual Tools):
10603 Tone down the advice against renaming or removing open files.
10604 (Limitations of Usual Tools): Add a new section, on 'rm'.
10606 2006-06-26 Stepan Kasal <kasal@ucw.cz>
10608 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
10609 -lXt in LIBS, idea from Karsten Hopp; this was due since
10612 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
10613 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
10614 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
10615 (which belong to Xt, not X itself). See Debian bug 327655.
10617 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10619 * configure.ac (AC_INIT): Bump to 2.60a.

10639 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
10641 * doc/autoconf.texi (Changed Directory Variables): New node,
10642 to document the whole `datarootdir' business a bit better.
10644 * tests/torture.at (datarootdir workaround): Extend test.
10645 Prompted by report by Alexandre Julliard.
10647 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
10649 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility

10659 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
10661 * NEWS: Use "M4" rather than "m4" when appropriate.
10662 Problem reported by Eric Blake.
10663 * doc/autoconf.texi: Likewise.
10664 Use @acronym around BSD, GCC, and GNU when appropriate.
10665 (Why GNU M4): Renamed from "Why GNU m4".
10666 (Redefined M4 Macros): Mention that Posix
10667 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
10668 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
10671 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10673 * bin/autom4te.in (handle_output): Do not forbid the empty
10675 * tests/tools.at (autoconf: the empty token): New test.
10677 2006-06-20 Stepan Kasal <kasal@ucw.cz>
10679 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
10680 calls, so that we do not care whether they are LIFO or FIFO;
10681 in the m4_wrap, do not check which diversion is the topmost
10682 one, just check that the stack is balanced at the end.
10683 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
10684 base diversion forever--pop the previous diversion before
10685 opening the new one; consequently, remove the m4_wrap call.
10686 * lib/autotest/general.m4 (AT_INIT): Likewise.
10687 * tests/m4sugar.at: Do not use
10688 m4_wrap([m4_diversion_pop([..])]), for educational purposes.

10691 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10693 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
10694 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
10695 Rework example of m4wrap token-pasting trouble so that it doesn't
10696 care whether it's LIFO or FIFO.
10697 Fix some "contrary to"s that are awkward in English.
10699 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10701 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
10702 to `yes' instead of `int$1_t' if the type is found, for more
10703 consistent configure output (where $1 is the number of bits).
10704 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
10705 Suggested by Bruno Haible.
10707 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
10708 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
10709 with system headers. Report by Bruno Haible.
10711 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10713 * config/config.guess, config/config.sub: Sync from upstream.
10715 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
10716 in order to avoid picking up an older installed frozen m4sh.m4f.
10717 Besides an outdated shell startup, this could have been created
10718 by an earlier M4 version with incompatible frozen file format.
10720 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
10722 * README: Recommend m4 1.4.4 instead of 1.4.3..

10724 (Special Chars in Names): Say that $(.FOO) is portable, as
10725 suggested by Stepan Kasal.
10726 (Installation Directory Variables, Build Directories):
10727 (Automatic Remaking, Subdirectories, Fortran Compiler):
10728 (Making testsuite Scripts, Defining Directories):
10729 Quote variable usages better.
10730 (Making testsuite Scripts): Add clean-local rule to makefile
10731 snippet, by Eric Blake.
10732 (Installation Directory Variables): Fix table item font.
10733 Reword slightly to clarify. Generalize advice about
10734 not using special characters to include all file-related
10735 vars, not just VPATH.
10736 (Special Chars in Variables): Warn about special characters in
10738 (Assignments): Clarify default-value example as suggested by
10740 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
10741 (Special Shell Variables): Note leading ./ or ../, as suggested
10743 (Limitations of Builtins): Under cd, warn about CDPATH.

10750 `@var', for texi2html.
10751 (Systemology): Some more word wrapping, for DVI output.
10752 (autom4te Invocation): The short option for `--melt' is `-M',
10755 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
10757 * doc/autoconf.texi: More formatting and English tweaks,
10758 many suggested by Ralf Wildenhues.
10759 Reword to avoid "@code{...}'s" and the like, since it's ugly
10760 with Emacs info mode. discontents -> woes.
10761 Put a few "will"s back. time stamp -> timestamp.
10762 side-effect -> side effect.
10764 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
10766 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
10767 Warn about $@ not persisting. Problem reported by Julien Danjou in
10768 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.

10774 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
10776 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
10778 * doc/autoconf.texi: Some systematic minor improvements, as
10779 follows. Use "makefile" when talking about makefiles
10780 generally (which might be named "makefile" or "Makefile" or even
10781 "foo.mk"), "Makefile" when talking about a specific makefile
10782 called "Makefile". This unclutters the text from weird quotes
10783 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
10784 values" rather than "@var{foo}s" and similar constructs containing
10785 "}s". Use "Make rules" rather than "Makefile rules". Minor
10786 English-language improvements. Change the prefix "sub-" to "sub"
10788 Put blank lines around examples more consistently.
10789 Avoid "rather" and "very" as intensifiers.
10790 Avoid "will" as an auxiliary.
10791 (Limitations of Make): Split this node into....
10792 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
10793 (Leading _ in Macro Names, Backslash-Newline-Newline):
10794 (Backslash-Newline Comments, Long Lines in Makefiles):
10795 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
10796 (obj/ and Make, make -k Status, VPATH and Make):
10797 (VPATH and Double-colon, $< in Explicit Rules):
10798 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
10799 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
10800 New nodes, resulting from splitup of Limitations of Make.
10801 All cross-references changed. Raise the top node from
10802 a section to a chapter, and all subnodes accordingly.
10803 Redo the introductory wording to match the new organization.
10804 (Installation Directory Variables): Use an example that is
10805 closer to what Autoconf actually does. Mention that VPATH's
10806 value should not contain metacharacters or white space.
10807 (Fortran Compiler): Fix a VPATH bug in an example.
10808 (Leading _ in Macro Names): Mention that this problem is no longer
10809 of practical concern.
10810 (VPATH and Make): Reword the advice to make it clearer
10811 that Autoconf and Automake support VPATH in non-GNU make, but
10812 many packages have bugs in this area.
10813 ($< in Explicit Rules): Refer to Build Directories rather
10814 than using a (non-VPATH-safe) example.
10815 (Automatic Rule Rewriting): Mention the sort of disaster that
10816 can ensue with Solaris-style rule rewriting with VPATH.
10818 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10820 * doc/install.texi (Compilers and Options): Weaken the
10821 suggestion to use GNU make for VPATH builds.

10827 in regular expression.
10829 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10831 * doc/autoconf.texi (Installation Directory Variables):
10832 Drop extra @samp from `@table @samp' item.
10833 (Limitations of Usual Tools): Comment fix.
10834 Do not nest @samp just to point to other table items.
10835 (Writing testsuite.at) <AT_CHECK>: The second argument to
10836 `@dvar' is already @samp'ed.
10837 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
10838 do not use @var in the second argument.

10842 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
10843 $as_shell.exe too. Problem reported by Andreas Buening in
10844 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
10846 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10848 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
10849 `unused variable' compiler warning, for `-Wall -Werror'.
10850 Reported by Jaap Haitsma in
10851 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
10853 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
10855 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
10856 case the compiler dumps core. Problem reported for
10857 OpenServer 5.0.7 by Tim Rice in
10858 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
10859 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
10862 2006-06-06 Tim Rice <tim@multitalents.net>.
10864 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
10865 "ERROR" only shows up in "make check" output if there is an

10870 * tests/tools.at (automatically allowed tokens): Fix typo.
10872 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10874 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
10876 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
10877 typically overflows on x86 CPUs, even though the C standard
10878 requires otherwise.
10880 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10882 * configure.ac (AC_INIT): Bump to 2.59e.

10889 * config/texinfo.tex: Sync from upstream.
10891 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
10892 seen, invoke libtoolize with `--ltdl' argument.
10893 * lib/autom4te.in (Autoreconf-preselections): Adjust.
10895 Suggested by Eric Blake.
10897 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
10899 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
10900 reported by Ralf Wildenhues.

10914 message issued by AC_REQUIRE.
10915 * tests/m4sugar.at: Check m4_require's error message.
10916 * tests/base.at: Check AC_REQUIRE's error message.
10917 * tests/local.at (AT_CHECK_M4): New macro, almost identical
10919 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
10921 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
10922 `expout' as the last parameter.
10923 * tests/tools.at: Adapt to the above change.
10925 2006-06-04 Stepan Kasal <kasal@ucw.cz>
10927 * doc/autoconf.texi (Limitations of Usual Tools): Correct
10928 information about race-free implementations of mkdir.
10930 2006-06-04 Eric Blake <ebb9@byu.net>
10932 * bin/autoreconf.in (help): Document M4 environment variable.
10933 * bin/autoconf.as (Usage): Likewise.

10939 * NEWS: GNU make now recommended for VPATH builds.
10940 Mention that some macros are now documented to be obsolescent.
10941 * doc/autoconf.texi:
10942 Prefer "current" to "modern" to describe
10943 currently-used (albeit perhaps old-fashioned) hosts.
10944 Mention which ancient features no longer need to be worried about.
10945 setgid -> set-group-ID
10946 setuid -> set-user-ID (these are the Posix terms)
10947 Fix some misuses of "only".
10948 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
10949 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
10950 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
10951 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
10952 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

10955 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
10956 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
10957 Mention that these macros are obsolescent.
10958 (Installation Directory Variables): shall -> should
10959 (File Descriptors): Mention that 0, 1, 2 might get reopened.
10960 Mention that it's now safe to use 3 and 4.
10961 (Limitations of Usual Tools): cp -r is now specified by Posix.
10962 Omit longwinded and obsolescent discussion of cp -f.
10963 Modernize discussion of expr, ls.
10964 (Limitations of Make): Modernize discussion of VPATH builds.
10965 Mention $? as a workaround in some cases.
10966 * doc/install.texi (Basic Installation):
10967 Mention "./configure; make; make install" first. Be more
10968 specific about why this file is generic. Remove unnecessary
10969 parens. Remove misleading "only". Remove obsolete advice
10970 about csh. Don't say "configure" takes awhile; say it
10971 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
10972 and CC=c99 rather than CC=c89, as these are blessed by current
10973 Posix. Recommend GNU make if doing a VPATH build.
10975 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
10977 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
10978 examples involving shell prompts.
10980 2006-06-02 Stepan Kasal <kasal@ucw.cz>
10981 and Paul Eggert <eggert@cs.ucla.edu>
10983 * doc/autoconf.texi (Here-Documents): Add details about the
10984 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
10985 use "here-documents" instead of "here documents".
10987 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
10989 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
10991 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
10993 * doc/autoconf.texi (File System Conventions): Warn about ":"
10994 anywhere in directory names.
10996 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
10998 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
10999 about quoting the case statement, just in case.
11000 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
11001 was fixed in ksh93g; reported by Ralf Wildenhues.
11003 2006-05-31 Stepan Kasal <kasal@ucw.cz>
11005 * doc/autoconf.texi (System Services): Do not document
11006 overriding EXEEXT via ac_cv_exeext=ext.
11007 (Particular Programs) <AC_PROG_MKDIR_P>:
11008 Document that ${MKDIR_P} understands --.
11009 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
11012 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11014 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
11015 argument with leading hyphen. Problem reported by Paul Eggert.
11017 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11019 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
11020 about quoting ac_try: quote all of it, if any of it seems suspicious.
11021 This means we don't have to worry about ${ or sed any more.
11022 Also, double-quote the case statement, to work around misuses via
11023 underquoting as reported by Ralf Wildenhues in
11024 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
11025 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
11026 undocumented and dangerous macro.
11027 Problem reported by Ralf Wildenhues in
11028 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.

11032 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
11033 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
11034 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
11036 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
11038 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
11039 since evidently some packages rely on the old, broken behavior.
11040 Problem reported by Ralf Wildenhues in
11041 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
11042 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
11043 pre-2006-05-26 definitions, but leave in the comments that
11044 these macros are dangerous and should not be used.
11045 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
11046 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
11047 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
11048 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
11049 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
11051 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
11053 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
11054 the use of 'tr', since this is our only use of 'tr'.
11056 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11057 and Paul Eggert <eggert@cs.ucla.edu>
11059 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
11060 Don't assume 'grep' works on long lines, since AIX grep doesn't.
11062 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11064 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
11065 the output file in the `${datarootdir}' test.
11067 2005-05-28 Stepan Kasal <kasal@ucw.cz>
11068 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11070 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
11071 mention of `datarootdir' in the input file(s), but literal
11072 `${datarootdir}' in the output file, and we haven't warned yet,
11073 then warn as well: the user may have (erroneously) used
11074 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
11075 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
11076 * tests/torture.at (datarootdir workaround): Extend this test.
11079 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11080 and Paul Eggert <eggert@cs.ucla.edu>
11082 * doc/autoconf.texi (autoheader Invocation): The first argument to
11083 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
11084 alternatives and clear up the language a bit.
11086 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
11088 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
11089 ac_config_guess, ac_config_sub, ac_configure.
11090 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
11091 Fix typo that prevented an unnecessary space from being removed.
11092 Problems reported by Ralf Wildenhues in:
11093 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
11095 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
11097 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
11098 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
11099 Don't use the term "thread-safe" to talk about mkdir race
11100 conditions, since the problem is more a process than a thread
11101 issue. Problem reported by Stepan Kasal in:
11102 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
11103 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
11104 the test for 'install' more closely. Look at MKDIR_P first.
11105 Look in the PATH, and at /opt/sfw/bin.
11106 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
11107 Don't bother to try mkdir -p, since we already check mkdir --version;
11108 just look at the version number. (There's no easy way to check
11109 for race-free implementations.)
11110 * tests/tools.at (autoconf: subdirectories): Adjust to above
11111 changes, since MKDIR_P now might end in "/mkdir -p".
11113 * doc/autoconf.texi (autoheader Invocation): Mention that the
11114 first arg of AC_DEFINE_UNQUOTED must be a literal.
11115 Problem reported by Ben Pfaff in
11116 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
11118 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
11119 * doc/autoconf.texi (Special Chars in Variables): New section.
11120 (Preset Output Variables): Warn about special chars in CPPFLAGS.
11121 (Installation Directory Variables): Quote $(datadir) better.
11122 (Limitations of Builtins): Describe some of eval's trickiness.
11124 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
11125 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
11126 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
11127 in front of every arg, not just trailing args. Quote apostrophes.
11128 (_AC_EVAL_ECHO): New macro.
11129 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
11130 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
11132 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
11133 exposed by quoting of eval argument. Put the command on line line
11135 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
11136 (_AC_PATH_X, AC_PATH_X): Quote more safely.
11137 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
11138 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
11139 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
11140 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
11141 Use eval more safely.
11142 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
11143 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
11145 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
11146 lines, exposed by quoting of eval argument.
11148 2006-05-26 Stepan Kasal <kasal@ucw.cz>
11149 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11151 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
11152 initialization of `ac_cv_exeext', do not override it if it was
11153 already set, unless it was set to `no', for compatibility with
11154 Autoconf-2.13, and comment this.
11155 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
11156 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
11157 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
11158 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
11159 Document that this test may be overridden by setting
11162 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11164 Revert these two patches:
11166 2006-04-06 Eric Blake <ebb9@byu.net>
11167 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
11168 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
11171 2006-04-01 Stepan Kasal <kasal@ucw.cz>
11172 Clean up _AC_COMPILER_EXEEXT* macros.
11173 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
11174 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
11175 ac_file to the name of the default output file and call
11176 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
11177 initial `rm' of the candidate files...
11178 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
11179 the same list in subsequent `rm' calls, and for the temporary
11180 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
11181 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
11182 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
11183 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
11184 no longer needed) by libtool. Make it a cache check.
11185 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
11186 copied here by mistake.
11187 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
11188 _AC_COMPILER_EXEEXT.
11189 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
11190 _AC_COMPILER_OBJEXT directly.
11191 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
11193 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11195 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
11196 Fix description of how the buggy `sed' works.
11198 2006-05-25 Noah Misch <noah@cs.caltech.edu>
11200 Sync from Automake:
11202 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
11203 ENOLCK. Only mention `make -j' when applicable. Only raise
11204 fatal errors when `make -j' is involved. Improve error message.
11206 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11208 * doc/autoconf.texi (Here-Documents): We now know more about
11209 the variable expansion in here documents bug.
11210 Thanks to Tim Rice and Stepan Kasal.
11212 * doc/autoconf.texi (Making testsuite Scripts): Add an example
11213 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
11215 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11217 * tests/autotest.at (Multiline command from M4 expansion):
11218 No failure to be expected if the shell quotes newlines in
11219 commands in the `set -x' output. Report by Tim Rice.
11222 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11224 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
11225 expansion in the here-documents used by config.status, as that
11226 runs afoul of the Korn shell version M-12/28/93d bug described in
11227 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
11228 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
11229 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
11231 2006-05-23 Jim Meyering <jim@meyering.net>
11233 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
11234 Fix typo introduced with 2006-04-02 change. It reversed the sense
11237 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
11239 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
11240 ac_dB slightly, to save bytes in the script.
11241 Max out at 50 lines, rather than 96; this is more likely
11242 (though not guaranteed) to avoid obscure 'sed' failures.
11244 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11246 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
11247 `tr -d -' as bad option argument. Work around this by deleting
11248 an unrelated character.
11249 Report by Tim Rice <tim@multitalents.net>.
11251 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
11252 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
11253 Stepan Kasal <kasal@ucw.cz>
11255 * doc/autoconf.texi (Particular Programs): Do not promise that
11256 we always prefer the GNU version of the program, and that we
11257 search according to PATH; both rules can have exceptions.
11258 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
11259 AC_PROG_SED. Move descriptions of limitations
11260 to the Limitations of Usual Tools section.
11261 (Limitations of Usual Tools) <sed>: Mention script length
11262 limitations with Solaris /usr/ucb/sed.
11263 <grep>: Fix wording for empty alternative. Mention that -c and
11264 -l should not be combined, and that -E and -F should not be
11267 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11268 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11270 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
11271 limits in Solaris 8 /usr/ucb/sed by testing a long script.
11273 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11275 * doc/autoconf.texi (Defining Symbols): Literal parameter of
11276 AC_DEFINE is now passed to m4_pattern_allow.
11277 * NEWS: Mention that; likewise for AC_SUBST.
11278 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
11279 the parameter to m4_pattern_allow.
11280 * tests/tools.at: Add a check for that.
11282 2006-05-22 Stepan Kasal <kasal@ucw.cz>
11284 * lib/autoconf/status.m4: Fix typos.
11286 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11288 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
11289 only the files that this macro generates.
11291 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11293 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
11294 the HP-UX sed limitation of 99 commands, labels do not count.
11295 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
11297 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
11299 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
11301 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
11302 Import the following fix from coreutils:
11304 2006-01-13 Jim Meyering <jim@meyering.net>
11306 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
11307 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
11308 not double-quote uses of that variable, to accommodate the rare
11309 case in which getmntent is available in none of the libraries
11310 checked. This happens at least on FreeBSD 5.0.
11312 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
11314 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
11315 ac_config_guess, ac_config_sub, and ac_configure, since evidently
11316 some other programs unwisely rely on these undocumented vars.
11317 But put in warning comments about them.
11318 Problem reported by Ralf Wildenhues in
11319 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
11320 * NEWS: Document that these variables are intended to go away.
11322 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11324 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
11325 and set the language to C++ (analogous to the equivalent Fortran
11328 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
11329 * doc/autoconf.texi (C++ Compiler): Document it.
11330 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
11333 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
11335 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
11336 that caused config.status to generate 100-command sed scripts; the
11337 portable limit is 99.
11339 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11341 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
11342 variable `ac_d' instead of `d' to avoid infringing namespace.
11343 Report by Ralf Menzel.
11345 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
11347 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
11348 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
11349 * tests/tools.at (autoconf: subdirectories): New test, taken from
11350 the corresponding problem report by Ralf Wildenhues in:
11351 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
11353 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
11354 Quote some uses of shell variables if they might suffer unexpected
11355 globbing. This doesn't fix all instances of quoting problems that
11356 I found, just the easy ones that look safe.
11357 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
11358 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
11359 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
11360 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
11361 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
11362 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
11363 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
11365 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
11366 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
11368 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11370 * bin/autoreconf.in ($help): Reword according to the manual.
11371 Suggested by Olly Betts.
11373 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
11374 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11376 * bin/autoreconf.in: Pass the directory argument to
11377 `require_configure_ac'. Fix comment.
11378 * tests/torture.at (Configuring subdirectories): Expose this.
11379 Reported by Olly Betts.
11381 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11383 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
11384 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
11385 Automake as follows:
11387 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
11388 `$configure_in' instead of `configure.in', to preserve
11389 directory component.
11391 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11393 * config/config.guess, config/config.sub, config/texinfo.tex,
11394 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
11396 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
11398 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
11399 test for C99 conformance; (bool) 0.5 is an integer constant
11400 expression, but (bool) -0.5 is not. Problem reported by Fedor
11401 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
11403 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
11405 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
11406 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
11407 Warn about obsolete install-sh files. Remove stray sentence
11408 fragment and fix cross reference.
11409 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
11410 install -d; this undoes the 2006-05-10 change.
11411 (MKDIR_P): Mark with AN_MAKEVAR.
11412 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
11413 that we don't require $INSTALL to be thread-safe. Move comments
11414 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
11415 of AC_PROG_INSTALL. Output a message saying that we're checking
11416 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
11417 MKDIR_P instead of AC_SUBST.
11418 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
11419 Special magic for MKDIR_P, too.
11420 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
11422 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
11424 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
11426 Sync from Automake, as follows:
11428 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11429 * config/install-sh: Initialize IFS, so field splitting isn't
11431 * config/mkinstalldirs: Likewise.
11432 * config/missing: Remove superfluous quotes. Replace all uses of
11433 `[' by `test', for consistency, and for..
11434 * config/missing (sed_minuso, sed_output): New variables.
11435 (autom4te, help2man, makeinfo): Use them. Unifies detection of
11436 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
11437 Fixes `missing' to detect `--output' for help2man. Fixes
11438 PR automake/483. Report by Dennis J. Linse.
11439 (autom4te): Document in `missing --help'.
11441 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11443 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
11444 * config/install-sh: Don't use 'path' to talk about file names,
11445 as per GNU coding standards. Close a race condition reported by Ralf
11446 Wildenhues and Stepan Kasal. There is still a race condition
11447 on hosts that predate Posix 1003.1-1992, but we can't help this.
11448 Don't mishandle weird characters like space on pre-Posix hosts.
11449 Invoke mkdir at most once per dir arg on pre-Posix hosts.
11450 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
11451 AC_PROG_MKDIR_P from AS_MKDIR_P.
11452 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
11453 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
11454 earlier editions are not (including Automake 1.8.3).
11455 Do not suggest mkinstalldirs for thread-safety.
11456 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
11457 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
11458 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
11459 presence of special characters and race conditions.
11460 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
11461 in Autoconf's name space.
11463 2006-05-10 Bruno Haible <bruno@clisp.org>
11464 and Paul Eggert <eggert@cs.ucla.edu>
11466 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
11467 from Automake with minor changes.
11468 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
11470 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
11472 * config/install-sh: Update to Automake CVS version, as follows:
11473 2006-04-25 Stepan Kasal <kasal@ucw.cz>
11474 * lib/install-sh: Simplify the expr implementation of dirname.
11475 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
11476 * lib/install-sh: Handle --, and diagnose unknown options.
11478 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11480 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
11481 `./autom4te' to create `./testsuite', since the `all' target
11482 will ensure its presence, but `installcheck' should not create
11483 the uninstalled wrappers.
11485 * tests/torture.at (Unusual Automake input files): Skip if we
11486 detect automake < 1.8.
11488 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11490 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
11491 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
11492 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
11495 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11497 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
11498 munge (multiple) white space and other oddities.
11499 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
11500 single quotes in variable assignment.
11501 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
11502 and similar failures by adding multiple spaces, tabs, and other
11503 special characters.
11504 Report and different test suggested by Francesco Romani
11505 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
11507 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
11508 single quotes, we only need to search for single quotes; this
11509 both simplifies the search pattern, and makes us less
11510 susceptible to `echo' variations for arguments not containing
11512 (_AC_ARG_VAR_VALIDATE): Likewise.
11514 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11516 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
11517 `$*' and IFS concatenation issue with traditional shells and
11518 bash-2.04. Report by Seanster@Seanster.com.
11520 2006-05-03 Bruno Haible <bruno@clisp.org>
11522 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
11523 precisely which Mac OS X versions have the od problem.
11525 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11527 * doc/autoconf.texi: Use @option systematically.
11529 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
11530 and Bruno Haible <bruno@clisp.org>
11532 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
11534 (Integer Overflow): Mention the special case of integer division
11537 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11539 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
11540 traditional shells like the Solaris one that do not use the
11541 first IFS character for assembling `$*'.
11542 Prompted by a related report from autoconf_bug@nro.ca.
11544 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
11545 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11547 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
11548 Mention more problems with the -e option.
11550 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11553 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
11555 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
11556 in URLs to improve DVI formatted output (requires texinfo 4.6).
11557 (System Services, Systemology, Shellology): Likewise.
11558 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
11561 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
11563 (Runtime): Fix macro argument names to match description:
11564 `action-if-found' -> `action-if-true' and similarly.
11565 (Obsolete Macros): Likewise.
11566 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
11567 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
11568 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.

11600 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
11602 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
11603 since as_me isn't set yet.
11605 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
11607 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
11608 a few minor bugs in this area.

11636 * lib/autoconf/functions.m4: Likewise.
11637 * lib/autoconf/general.m4: Likewise.
11638 * lib/autoconf/headers.m4: Likewise.
11640 * doc/autoconf.texi (Run Time): Document the exit status situation
11641 with more accuracy and detail.
11643 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11645 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
11646 Archive is not officially `GNU' any more. Update URL.
11647 (Defining Directories): Likewise
11648 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
11650 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11652 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
11653 newline from the `trap' code to finish `config.log'; the NetBSD
11654 /bin/sh resets the exit status after an empty command, as
11655 documented in doc/autoconf.texi.
11656 Reported by Dalibor Topic <robilad@kaffe.org>.
11658 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
11660 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
11661 Suggested by Bruno Haible.
11663 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
11665 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
11666 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
11667 Instead, just list the shells that we know work.
11668 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
11669 changed. Be more cautious about the _cv_ variable.
11670 * tests/tools.at (Syntax of the shell scripts): Check the
11671 _cv_ variable once, at first, to avoid an internal autoconf error
11672 when sh -n does not work.
11674 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11676 * lib/Autom4te/FileUtils.pm: Sync from Automake.
11678 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
11680 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
11681 use ">&-" since we're only 99.999% sure that this is portable,
11682 and since the MinGW bug is fixed in a different way.
11683 * lib/autotest/general.m4 (AT_INIT): Likewise.
11685 2006-04-16 Stepan Kasal <kasal@ucw.cz>
11687 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
11688 before opening config.log, to avoid hitting a bug on MinGW.
11690 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
11692 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
11693 AS_MESSAGE_LOG_FD before reopening it onto the log file.
11694 This works around a MinGW bug reported by Eric Paire.
11695 Make sure that all writes to the log file append to it,
11696 rather than possibly losing data.
11697 * lib/autotest/general.m4 (AT_INIT): Likewise.
11699 2006-04-14 Stepan Kasal <kasal@ucw.cz>
11701 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
11704 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11708 * configure.ac (AC_INIT): Bump to 2.59d.
11710 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11714 * Makefile.maint (news-date-check): Do not require a leading `*'
11715 before the release date in NEWS.
11717 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11718 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11720 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
11721 the instantiated file do not contain the string 'datarootdir'
11722 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
11723 @mandir@, replace the reference '${datarootdir}' by the value.
11724 * tests/torture.at (datarootdir workaround): New test.
11725 * NEWS: Advertise this temporary fixup.
11726 Based on a patch by Bruno Haible, reported and analyzed by
11727 Paul Eggert and Noah Misch.
11729 2006-04-12 Eric Blake <ebb9@byu.net>
11731 * tests/autotest.at (Debugging a failed test): Fix comment.
11733 2006-04-12 Stepan Kasal <kasal@ucw.cz>
11735 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
11736 all the changes since 2006-04-07.
11738 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11740 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
11741 succeeded, but `ln -s file dir' failed, take care to remove the
11742 leftover target before the next test, to prevent its spurious
11743 failure; also make sure `ln file dir' works before selecting it.
11744 Thanks to Keith Marshall for pointing this out.
11747 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
11748 assignments in `at_debug_args', so that we put them correctly
11749 in the `run' script.
11750 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
11751 Reported by Eric Blake.
11753 2006-04-11 Eric Blake <ebb9@byu.net>
11755 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
11756 top-level tests after micro-suite has been run. Used in...
11757 (Debugging a successful test, Debugging script and environment),
11758 (Debugging a failed test): ...these new tests. The first of these
11760 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
11761 macro, split out from...
11762 (AT_INIT): ...here, so that using -d also generates a run script.
11763 Document that -d inhibits top-level logging.
11764 * doc/autoconf.texi (testsuite Invocation): Document that -d only
11765 inhibits top-level logging; debug scripts are created.
11767 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
11769 * tests/autotest.at (Empty test, Empty check): New test to check it.
11771 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
11774 2006-04-10 Stepan Kasal <kasal@ucw.cz>
11776 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
11777 the files if a problem appears. Make the empty *.at files
11778 read-only, too. Proposed by Ralf Wildenhues.
11780 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11782 * config/Makefile.am: Add comment to force updated Makefile.in.
11784 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
11785 space only patch to this file, this patch causes the Makefile.in
11786 files that include freeze.mk to be updated, and thus have a
11787 newer time stamp again, which in turn makes a pristine CVS
11788 checkout have correct time stamps.
11790 * Makefile.maint (cvs-sv): New macro, to be used..
11791 (config.guess-url_prefix, config.sub-url_prefix)
11792 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
11793 point to CVS text checkout of Gnulib files.
11794 (copyright-check): Bump current year.
11795 (announcement): Do not hard-wire `./announce-gen'.
11796 (cvs-update): Propagate failures of `cvs' and `move-if-change'
11798 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
11800 (wget_files): Update config.guess, config.sub, texinfo.tex by
11801 `wget-update', now that their URLs work again.
11803 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11805 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
11806 Problem noted by Paul D. Smith.
11808 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11810 * doc/autoconf.texi: Remove unused words from word list.
11811 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
11812 .x-sc_trailing_space: New files.
11814 * doc/standards.texi: Sync from gnulib.
11816 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
11817 `LIBOBJDIR' as experimental.
11819 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
11820 with a target directory; it's internally implemented as `cp'
11821 anyway, but since Autoconf advertises the possibility to use
11822 a target directory when LN_S is `ln -s', we need to find out.
11823 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
11824 analyzed by Keith Marshall <keith.marshall@total.com>.
11828 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
11830 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
11831 confdefs.h as-is. In general, if it has backslash-newline or the
11832 like, then it doesn't work either to sort or to remove empty
11835 2006-04-09 Stepan Kasal <kasal@ucw.cz>
11837 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
11839 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
11841 * lib/autom4te.in (Automake-preselections): Preselect
11844 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11846 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
11847 apostrophe within a single-quoted string, as this is the usual
11848 tradition and is easier to read than '"'"'. Don't rely on the
11849 shell treating "$/" like '$/'. Use a more-consistent indenting
11850 style for the trap.
11852 2006-04-09 Eric Blake <ebb9@byu.net>
11854 * tests/autotest.at (Backquote command substitution),
11855 (Multiline backquote command substitution): Remove mistaken
11856 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
11858 (Parenthetical command substitution, Multiline parenthetical
11859 command substitution): here.
11861 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
11863 Import macros from gnulib (often changing their name).
11865 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

11885 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
11886 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

11890 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
11891 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
11892 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
11893 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
11894 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
11895 (C Compiler): Move AC_C_LONG_DOUBLE to ...
11896 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
11897 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
11898 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
11899 (Coding Style). Don't mention m4_expand_once.
11900 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via

11910 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
11911 Catch a bug in an HP-UX C compiler.
11912 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
11913 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

11917 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
11920 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
11921 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
11923 2006-04-08 Stepan Kasal <kasal@ucw.cz>
11925 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
11926 of the warning introduced by the 2001-08-28 change.
11928 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
11929 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11931 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
11932 variables shall be overriden by the cache.
11933 * tests/torture.at (AC_ARG_VAR): Test also with a first value
11934 that contains braces.
11936 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11938 Revert the patch from 2006-04-01 and only improve
11939 _AS_DETECT_BETTER_SHELL:
11941 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
11942 skip nonexistent directories.
11943 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
11944 only shell candidates which exist.
11945 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
11946 * lib/autotest/general.m4 (AT_INIT): No need to give three
11947 parameters to _AS_PATH_WALK.
11949 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
11950 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11952 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
11953 distinguish m4sugar macros.
11954 * tests/tools.at (autoupdating with aclocal and m4_include):
11955 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
11956 test case by Noah Misch <noah@cs.caltech.edu>.
11958 2006-04-07 Stepan Kasal <kasal@ucw.cz>
11960 Revert my change from 2006-03-17, in other words:
11961 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
11963 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
11964 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
11967 2006-04-07 Eric Blake <ebb9@byu.net>
11969 * doc/autoconf.texi (Programming in M4sh): Document that
11970 AS_MKDIR_P exits the script on failure.
11971 * lib/autotest/general.m4: Remove redundant AS_ERROR.
11973 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11975 * config/elisp-comp, config/install-sh, config/mdate-sh,
11976 config/missing, config/mkinstalldirs: Sync from Automake.

11990 Eric Blake <ebb9@byu.net>,
11991 Paul Eggert <eggert@cs.ucla.edu>,
11992 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
11994 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
11995 whether `set' quotes correctly: redirect stderr of the tested
11996 `set', and use a subshell, for Ultrix; use `sed' instead of
11997 `grep' for zsh `set' which may write binary output; match only
11998 at the beginning of a line, to avoid false positives.
11999 In order to avoid false positives by unrelated variables with
12000 multiline content, put the dump algorithm in a subshell and
12001 unset all variables containing newlines (except some which are
12002 special to the shell). Warn about cache variables that are
12005 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12007 * config/config.guess, config/config.sub, config/texinfo.tex:
12008 Sync from upstream.
12010 * tests/mktests.sh: Reword comments.
12012 * tests/mktests.sh: Only skip internal macros starting with
12013 `_AC_' or `__AC_'. Noted by Stepan Kasal.
12014 Update exclusion lists for the test suite to this end:
12015 (AC_ARG_VAR): Do test this now.
12016 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
12017 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
12018 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
12019 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
12021 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
12022 shell issue with double-quoted command substitutions of native
12024 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
12027 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

12030 (sc_cast_of_x_alloc_return_value): Likewise.
12031 (sc_cast_of_alloca_return_value, sc_error_exit_success)

12035 (sc_tight_scope): Do not fail for non-existing `src' directory.
12036 (sc_changelog): Skip the Copyright footer.
12037 * lib/autoconf/lang.m4: Remove trailing space.
12039 * lib/autoconf/status.m4: More replacements to
12040 <tab><space> where this makes sense.
12042 2006-04-06 Stepan Kasal <kasal@ucw.cz>
12044 * tests/Makefile.am (maintainer-check-posix):
12045 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
12047 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
12048 ac_config_<foo>s again, sometimes normalized, sometimes not.
12049 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
12050 (AC_CONFIG_COMMANDS): Do not do so here.
12051 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
12052 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
12053 2005-07-25 rewrite. Noticed by Noah Misch.
12055 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
12056 _AC_PRESERVE_HELP_ORDER, ...
12057 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
12059 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
12060 inside m4_expand_once; it is redundant.
12062 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
12063 for --help from Cygnus `configure.'
12065 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
12067 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
12068 on a patch proposed by Ralf Wildenhues.
12070 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
12072 * lib/autoconf/status.m4: Replace <space>''<tab> with
12073 <tab><space> where this makes sense.
12075 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
12076 Noah Misch <noah@cs.caltech.edu>

12088 tests/mktests.sh, tests/torture.at: White space cleanup:
12089 remove some SPACE before TAB, or add quoting ('' or @&t@).

12118 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
12119 Use 'comm' rather than N instances of grep; this also fixes a bug

12214 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
12215 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
12216 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
12217 no longer needed) by libtool. Make it a cache check.
12218 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
12219 copied here by mistake.

12985 2005-10-20 Jim Meyering <jim@meyering.net>
12987 * doc/autoconf.texi: Typo: s/feature/features/ in ``the features of
12988 the latter'', in two places.
12990 2005-10-19 Paul Eggert <eggert@cs.ucla.edu>
12992 * doc/autoconf.texi (Generating Sources): AC_LANG_PROGRAMS ->
12993 AC_LANG_PROGRAM, fixing a typo. Don't give details about
12994 the inner workings of AC_LANG_FUNC_LINK_TRY.
12995 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
12996 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
12997 by the function rather than ignoring it.
12998 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
12999 comparing its address. Intel's interprocedural optimization was
13000 outsmarting the old heuristic. Problem reported by
13003 2005-10-19 Stepan Kasal <kasal@ucw.cz>
13005 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
13007 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
13009 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
13010 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
13012 2005-10-04 Stepan Kasal <kasal@ucw.cz>
13014 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
13015 before removing it (chmod -R u+rwx); there are three instances of this.
13017 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13018 Stepan Kasal <kasal@ucw.cz>
13020 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
13021 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
13022 make its content writable before removing it. Remove an errorneous
13023 comment from the end, where the logs of the failed tests are copied
13024 to the main log file.
13026 2005-09-27 Stepan Kasal <kasal@ucw.cz>
13028 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
13029 in case the computer is too quick. Double quote the configure.ac
13032 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
13033 problems if the testsuite were running too fast.
13035 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
13037 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
13038 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
13039 (which belong to Xt, not X itself). See Debian bug 327655.
13040 * NEWS: Mention this.
13042 2005-09-07 Stepan Kasal <kasal@ucw.cz>
13044 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
13046 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
13048 * config/move-if-change: Don't output "$2 is unchanged";
13049 suggested by Ben Elliston. Handle weird characters correctly.
13051 2005-09-06 Stepan Kasal <kasal@ucw.cz>
13053 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
13054 calls, so that the final expansion of this macro is shorter.
13055 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
13056 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
13057 the cleanup there. Use AS_VAR_* macros, to be more general.
13058 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
13060 * lib/autoconf/general.m4: Use AS_IF where appropriate.
13062 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
13064 2005-09-01 Stepan Kasal <kasal@ucw.cz>
13066 * doc/autoconf.texi (Configuration Headers): Add an index entry
13069 2005-08-26 Pavel Roskin <proski@gnu.org>
13071 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
13072 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
13075 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
13077 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13078 The previous patch didn't work, so try a better one.
13080 2005-08-26 Stepan Kasal <kasal@ucw.cz>
13082 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
13083 in the example. Reported by Bruno Haible.
13084 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
13085 "if $undefined_var;" succeeds with my shell.
13087 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
13088 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
13089 but change the m4_divert_text to m4_divert_once.
13091 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
13093 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
13094 Work around bug in Solaris /usr/xpg4/bin/awk.
13095 The bug is present in at least Solaris 8 through 10.
13097 2005-08-24 Stepan Kasal <kasal@ucw.cz>
13099 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
13100 some evil values and relying on the fact that $* concatenates the
13101 parameters by the first character from IFS.
13103 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
13104 Stepan Kasal <kasal@ucw.cz>
13106 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
13107 first header appears, define AH_HEADER.
13108 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
13109 Update limitations about when to call AC_CONFIG_HEADERS.
13110 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
13111 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
13112 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
13113 ``Configuration Actions''; fix their index entries.
13115 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
13116 options correctly. Process N-M as M-N if M is smaller than N.
13117 Process ranges correctly so that N-N will run only N.
13118 Sort and uniquify the tests that will be run. If there is more
13119 than one test, reinsert the banners for the tests.
13120 * tests/autotest.at (Keywords): Unmark XFAIL.
13122 2005-08-23 Stepan Kasal <kasal@ucw.cz>
13124 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
13125 before passing the macro name to AH_TEMPLATE.
13127 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
13128 now opens log after option processing; in particular, --version
13129 and --help do not touch config.log.
13131 * Makefile.maint: Revert the change from 2005-08-12.
13133 2005-08-22 Stepan Kasal <kasal@ucw.cz>
13135 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
13137 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
13139 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13141 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
13142 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
13145 * doc/autoconf.texi (Defining Symbols, Changed Results):
13146 Prepend to LIBS, not append, in examples.
13148 2005-08-16 Stepan Kasal <kasal@ucw.cz>
13150 When building in place, set srcdir="."; suggested by Tim Van Holder.
13152 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
13153 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
13154 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
13155 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
13156 does not mean "no --srcdir option".
13158 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13160 * tests/autoscan.at (autoscan): New file.
13161 * tests/suite.at: Use it.
13162 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
13163 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
13165 * tests/autotest.at (Keywords): Test keywords combinations.
13167 2005-08-12 Stepan Kasal <kasal@ucw.cz>
13169 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
13170 add "2>&1"; gzip 1.2.4 prints help on stderr.
13172 2005-07-27 Stepan Kasal <kasal@ucw.cz>
13174 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
13175 was pushdef'ed twice while popped only once. Push it only once.
13176 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
13178 2005-07-26 Stepan Kasal <kasal@ucw.cz>
13180 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
13181 prefixed by mere "===", not "configure: === ".
13183 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
13185 * Makefile.maint: Update from Bison.
13187 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
13188 "<tab>" in comment, so that the point is understandable.
13190 2005-07-25 Stepan Kasal <kasal@ucw.cz>
13192 Rewrite substantial part of lib/autoconf/status.m4.
13193 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
13194 and CONFIG_COMMANDS are not processed in four separate loops.
13195 Instead, there is one main loop. This alows that the common code
13196 is expanded only once, thus config.status (and configure) is smaller.
13198 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
13199 the AC_LIST_FILES and cousins macros are no longer used.
13201 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
13202 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
13203 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
13204 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
13205 contain the initialization, nor the for loop, nor the associated
13206 commands; all these go to ...
13207 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
13208 _AC_OUTPUT_CONFIG_STATUS.
13209 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
13210 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
13211 (_AC_OUTPUT_FILE): The creation of the sed script ...
13212 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
13213 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
13214 _AC_OUTPUT_MAIN_LOOP.
13215 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
13216 _AC_CONFIG_COMMANDS): Use ...
13217 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
13218 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
13219 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
13220 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
13221 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
13222 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
13224 (_AC_CONFIG_UNIQUE): Update.
13225 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
13226 Replaced by this ...
13227 (_AC_LIST_TAGS): ... new common macro.
13228 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
13229 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
13230 (_AC_LIST_TAG_COMMANDS): ... new common macro.
13231 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
13232 this didn't belong to the `config commands' section.
13233 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
13234 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
13235 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
13236 to the `config commands' section either.
13237 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
13238 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
13240 ... and many changes to the comments nearby.
13242 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
13243 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
13244 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
13245 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
13246 (#define header templates): The comment at the top of the generated
13247 header now includes the name(s) of the source file(s).
13249 Several unrelated small changes:
13251 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
13252 parameter to AC_DIAGNOSE.
13253 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
13254 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
13255 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
13256 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
13257 with AU::AC_OUTPUT.
13258 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
13259 in AC_OUTPUT doesn't double-quote it either.
13260 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
13263 2005-07-10 Stepan Kasal <kasal@ucw.cz>
13265 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
13266 versions of Portland Group compiler produce single- and double-quoted
13267 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
13268 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
13270 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
13272 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13273 This is a corrected version of yesterday's patch.
13275 2005-07-07 Stepan Kasal <kasal@ucw.cz>
13277 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
13278 path, too; insert a "===" to emphasize the line.
13280 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
13281 ac_cv_build_alias to ac_build_alias.
13282 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
13284 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
13285 change eliminates it. Problem reported by Alexandre Duret-Lutz.
13286 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
13287 (AC_ARG_VAR): ... here.
13288 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
13291 Keep a list of all precious variables and process them with one simple
13292 for loop, instead of expanding all commands, or, OTOH, complicated
13293 processing of output of "set".
13294 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
13295 variable names in new macro...
13296 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
13297 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
13298 a loop to assign all ac_env_* and ac_cv_env_* variables.
13299 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
13301 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
13302 its value to shell variable ac_precious_vars and call
13303 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
13304 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
13305 _AC_ARG_VAR_VALIDATE.
13307 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
13308 and the AC_SUBSTs ...

13312 the ac_subst_files section in config.log.

13320 * lib/autoconf/c.m4 (AC_C_TYPEOF): New macro.
13321 * tests/c.at (C keywords): Test AC_C_TYPEOF.
13323 Fix problems reported by Nicolas Joly.
13324 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
13325 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
13326 They are generated by the Tru64 v5.1B shell.
13328 2005-07-05 Stepan Kasal <kasal@ucw.cz>
13330 Fix my changes from 2005-07-01; reported by Noah Misch.
13331 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
13332 description, the macro now accepts only a single tag.
13333 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
13335 Fix cases when the varsions of Autoconf and Autotest don't match.
13336 Reported by Noah Misch.
13337 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
13338 at_top_builddir, for compatibility with older autotest.
13339 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
13340 is not set, use at_top_builddir, for compatibility with older
13341 versions of autoconf.
13343 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
13345 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
13346 Problem reported by Patrick Welche.
13348 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
13350 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
13351 sed substitution command, so that we allow | in program prefixes
13352 and program suffixes. (& is a problem anyway; we're not fixing
13354 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
13355 configure_input, top_builddir, srcdir, etc.
13356 * lib/autotest/general.m4 (AT_INIT): Likewise, for
13357 PATH_SEPARATOR in AUTOTEST_PATH.
13359 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
13361 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
13362 for loop over config.site files using `set', to allow
13363 directory names containing IFS characters.
13365 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
13367 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
13368 directories with weird names. Apparently some people like living
13369 on the edge. However, improve the test that "pwd" actually does
13370 report a name for the working directory.
13371 * NEWS: Remove the claim that we test for funny chars in dir names.
13373 2005-07-01 Stepan Kasal <kasal@ucw.cz>
13375 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
13377 * lib/m4sugar/m4sugar.m4 (m4_foreach_w): ... by this new macro.
13378 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES, _AC_CONFIG_UNIQUE):
13379 Now accept a single tag, not whitespace separated list.

13382 2005-06-30 Stepan Kasal <kasal@ucw.cz>
13384 * doc/autoconf.texi (Configuration Headers): Change the explanation
13385 about #include <config.h>.
13386 (Generic Functions): Mention the Gnulib project.
13387 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
13389 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
13390 document to output the default config_* lists to config.status.
13391 Don't recognize option --file, if the functionality is not there.
13392 Likewise for --header; moreover, recognize --he and --h as shortcuts
13393 for --help in that case.
13395 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
13396 matches the order of execution. No code changed.
13398 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13400 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
13401 single-quoted -cmdline argument in Portland Group compiler.
13402 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
13404 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>
13406 * lib/autom4te.in (Automake-preselections): Preselect AC_SUBST_TRACE.
13408 2005-06-29 Stepan Kasal <kasal@ucw.cz>
13410 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
13411 descriptors to child processes; reported by Norman Gray.
13413 2005-06-29 Stepan Kasal <kasal@ucw.cz>
13415 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
13417 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
13418 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
13419 (AC_SUBST): Call it.
13420 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
13421 the directory specific variables; but don't call it for configure_input.
13423 2005-06-28 Derek Price <derek@ximbiot.com>
13425 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
13428 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
13430 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
13431 directory have inherent problems with special characters like spaces,
13432 due to limitations in Make syntax. Problem reported by Alexandre
13434 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
13435 Also, fix Tru64 porting problem with shell patterns,
13436 reported by Ralf Wildenhues.

13446 Fix some more shell quoting problems. Prompted by a bug report
13447 from Justace Clutter.
13448 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
13449 variable into diagnostic. Make the diagnostic an error, not a warning,
13450 because we really don't support spaces and suchlike in dir names.
13451 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
13452 Don't worry about backslashes in srcdir; it can't happen now.
13453 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
13454 Simplify ac_optarg handling.
13455 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.
13457 2005-06-22 Stepan Kasal <kasal@ucw.cz>
13459 Fix AT_CONFIG_CMP for Solaris hosts; idea from Ralf Menzel.
13460 * configure.ac: Call AC_PROG_EGREP and AC_PROG_SED.
13461 * tests/atlocal.in: Propagate $EGREP and $SED.
13462 * tests/local.at (AT_CHECK_ENV): Use $EGREP, not $GREP -E.
13463 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
13465 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
13466 that '\|' is not allowed in BREs; recommend using newline separated
13467 list of patterns instead of multiple -e options.
13469 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
13471 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

13477 2005-06-21 Stepan Kasal <kasal@ucw.cz>
13479 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
13480 b, t, r, w commands require single space, while : cannot have any.
13481 (Special Shell Variables): Fix sed code this in the example.
13482 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
13483 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
13485 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
13486 expand to the empty list. Don't use two pairs of m4_changequote,
13487 it's not necessary.
13489 2005-06-20 Derek Price <derek@ximbiot.com>
13491 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
13493 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
13495 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
13496 * doc/autoconf.texi:
13497 Don't mention Solaris versions so much, if a
13498 problem is common to all extant versions of Solaris. Say "SunOS
13499 4" instead of "SunOS" for SunOS 4.
13500 (awk): Mention more of the limitations of traditional Awk.
13501 (cat): Don't talk about cat -v.
13503 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
13505 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
13506 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
13507 but the implementation is entirely different and is designed
13508 to be compatible with glibc strverscmp.
13509 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
13511 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug

13514 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
13515 Use shell builtins rather than 'expr', to work around expr bug.
13517 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
13519 * doc/autoconf.texi: "filesystem" -> "file system".
13520 "behaviour" -> "behavior".
13521 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
13522 * lib/autoconf/general.m4: Omit blank after ":" sed command,
13524 * lib/m4sugar/m4sh.m4: Likewise.
13525 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
13526 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
13528 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
13529 (.x.1): Ignore the time stamp in the .TH line when deciding whether
13530 to update the man page. That way, we don't have to check in new
13531 man pages every month.
13533 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
13534 quotes and backslashes. Patch from Derek Price.
13536 2005-06-10 Derek Price <derek@ximbiot.com>
13538 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &

13543 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
13544 -u, since it outputs chatter if the input files are the same.
13545 Problem reported by Ralf Menzel.
13547 2005-06-08 Derek Price <derek@ximbiot.com>
13549 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
13550 renaming them since they are about to be redefined anyhow.
13552 2005-06-08 Derek Price <derek@ximbiot.com>
13554 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
13555 redefined M4 macros to this node. Document m4_include & m4_sinclude.
13556 Move m4_undefine to alphabetical order.
13558 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
13560 * README: Recommend GNU M4 1.4.3 or later.
13561 * doc/autoconf.texi (Introduction): Likewise.
13562 Reword to avoid some formatting glitches.
13563 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
13564 Clarify explanation of HP compiler bug.
13565 Redo example output tp match current CVS snapshot.
13566 Use @example.org in email addresses when the examples
13567 might get inadvertently cut-and-pasted into user code.
13568 Remove example of autom4te usage that doesn't seem to work now.
13569 Use modern AC_INIT (except when the example is meant to be
13570 shown with Autoconf 2.13).
13571 Update ksh info for Solaris 9 and later.
13573 Modernize description of Automake versions a bit.
13574 Don't claim a future version of Autoconf is near.
13575 * doc/install.texi: Reword to avoid some formatting glitches.
13577 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13579 * doc/autoconf.texi: Add [] to examples, so that the manual
13580 follows its own advice about quoting better.
13581 Reword to avoid some formatting glitches.
13582 * doc/installt.exi: Reword to avoid some formatting glitches.
13584 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
13585 Tru64 ksh pattern matching bug. Reported against Libtool by
13586 Albert Chin <libtool@mlists.thewrittenword.com> and
13587 Nicolas Joly <njoly@pasteur.fr>.
13589 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13591 m4_cdr of one-member list was [[]] (one-member list containing an
13592 empty string) instead of [] (an empty list. Callers were skewed to
13593 match this misbehaviour. As a consequence of this:
13594 - m4_foreach([x], [], [foo]) expanded to `foo', while
13595 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
13596 This bug has been fixed:
13598 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
13599 expand to an empty string; print error msg if called without
13601 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
13602 misbehaviour; handle [] and [[]] correctly.
13604 2005-06-06 Stepan Kasal <kasal@ucw.cz>
13606 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
13607 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
13608 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
13610 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
13612 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
13613 swallow records with more than 99 fields.
13614 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
13615 parse the long line.
13617 2005-06-04 Stepan Kasal <kasal@ucw.cz>
13619 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
13620 swallow literals longer than 399. Reported by Ralf Wildenhues.
13621 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
13622 to workaround this limitation.
13624 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
13626 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
13627 to gfortran, and make these the first two compiler names
13628 checked (following the general autoconf preference for gcc).
13630 2005-06-03 Stepan Kasal <kasal@ucw.cz>
13632 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
13633 (DISTCLEANFILES): Remove $(check_SCRIPTS).
13634 (testsuite): Make sure autotest.m4f is up-to-date before using it.
13636 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
13638 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
13639 expression of unbounded size when processing the --list
13640 option. This runs afoul of a limit of 399 bytes per regular
13641 expression on AIX. Problem reported by Ralf Wildenhues.
13643 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
13645 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
13646 * doc/autoconf.texi (Particular Headers): Reword example
13647 for multiline stdbool replacement.
13648 (Setting Output Variables): Reword text a bit. Don't
13649 give all the details about |#_!!_#|.
13650 Reword description of line replacement.
13652 2005-05-31 Dan Manthey <dan_manthey@partech.com>
13654 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
13655 now contain newlines, and substituted files must be referenced on
13656 a line alone; the sed scripts to substitute them are now very
13658 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
13659 commands can be put in a sed script portably.
13660 * doc/autoconf.texi (Setting Output Variables): Document above
13661 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
13662 use of multiline substitution.

13668 From Ralf Menzel (trivial change).
13670 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
13672 * tests/local.at: Don't attempt to check for negated character
13673 classes in shell scripts. The test was too brittle.
13675 2005-05-25 Stepan Kasal <kasal@ucw.cz>
13677 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
13678 * doc/autoconf.texi (Limitations of Builtins): Document this
13681 2005-05-24 Stepan Kasal <kasal@ucw.cz>
13683 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
13684 common code; used in many places in the tree.
13685 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
13686 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
13688 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
13690 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
13691 messages when ac_unique_file is not found.
13692 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
13693 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
13694 commands, for consistency with AC_MSG_ERROR and such.
13696 * bin/autoconf.as: Make more use of "shift 2" in option processing.
13698 * bin/Makefile.am: Merge the two rules for creating scripts.

13703 obsolete; it was never documented.
13704 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
13706 2005-05-20 Stepan Kasal <kasal@ucw.cz>
13708 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
13709 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
13710 (ac_top_builddir): ... this ...
13711 (ac_top_build_prefix): ... to this; the old name is also kept, for
13712 backward compatibility.
13713 (ac_top_builddir_sub): New variable, without the trailing slash,
13715 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
13716 * doc/autoconf.texi (Configuration Actions): Rename
13717 ac_top_builddir to ac_top_build_prefix.
13718 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename

13729 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
13730 argument to m4_foreach. I guess it was necessary in the past,
13731 but I think it's a no-op now.
13733 2005-05-17 Stepan Kasal <kasal@ucw.cz>
13735 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
13736 ``cat <<_ACEOF'' commands to one.
13737 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
13738 * lib/autoconf/status.m4: On various places, use expr instead of
13740 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
13741 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
13742 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
13744 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
13745 the wrong patterns between ``case'' and ``esac.'' The previous
13746 code had false positives.

13815 quoting rules. Problems noted by Stepan Kasal.
13816 Also, throughout this document, be more careful about white space.
13817 "blank", "white space", and "space" all have different meanings
13818 and we should be careful to say what we mean.

13857 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
13858 by AC_DEFINE; it was a mistake.

13867 * doc/autoconf.texi (External Software): Quadrigraphs are not
13868 processed correctly in AS_HELP_STRING; avoid this in the examples.
13869 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
13870 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
13871 comment and reduce m4_default([foo], []) to [foo].
13872 (m4_strip): Update the explanation.
13874 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
13876 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
13877 Remove core.conftest.* too; it's generated by Tru64 5.1.
13878 Problem reported by Jennis Pruett.
13879 * lib/autoconf/functions.m4
13880 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

13908 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
13910 * doc/autoconf.texi (Particular Functions): Use gnulib's current

13928 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
13929 Merge `-z option' as well for the benefit of Solaris link flags. Pass
13930 whole-archive (-zallextract, -zdefaultextract) options in the hope of
13931 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
13932 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.

13936 * NEWS: The configure command now warns you if you attempt to use
13937 a directory whose name contains a special character like space,
13939 * doc/autoconf.texi (Installation Directory Variables): Allow

13953 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
13954 ac_pwd, and quote srcdir.
13955 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
13957 * doc/autoconf.texi: Fix some systematic formatting problems.
13958 ".)" needs a following @: if not at the end of a sentence, and
13959 similarly for "!)". "etc." should be preceded by a comma.
13960 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
13962 2005-03-22 Bruno Haible <bruno@clisp.org>
13964 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
13965 argument is often called 'build-aux'.
13967 2005-03-07 Stepan Kasal <kasal@ucw.cz>
13969 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
13970 macro AC_TRY_LINK is obsolete.
13971 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
13974 2005-02-24 Stepan Kasal <kasal@ucw.cz>
13976 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
13977 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
13978 from a Common Lisp's `cl'.
13979 (AC_PROG_CXX): Behave according to the documentation: don't
13980 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
13981 make the variable CCC precious; use `cl.exe', not `cl'.
13983 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
13984 Alexandre Duret-Lutz <adl@gnu.org>
13986 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
13987 /dev/null, as "configure" shouldn't read stdin, and this insulates
13988 us from problems (e.g., when testing for "cl"). Also, do this
13989 redirection before invoking "hostname" or "uname", and keep the
13990 original input stream available via...
13991 (AS_ORIGINAL_STDIN_FD): ... this new macro.
13992 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't

14002 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
14004 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
14005 newline if neither \c nor -n work, as that would output two
14006 newlines. Prefer -n to \c. Reported by Stepan Kasal.
14008 2005-02-12 Stepan Kasal <kasal@ucw.cz>
14010 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
14011 This causes that any required macros inside will get before the if.
14012 * doc/autoconf.texi (autom4te.cache): A typo.
14014 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
14016 Undo previous change, except keep the change to
14017 lib/autoconf/programs.m4 that replaced grep with shell
14018 pattern-matching. This is because net-snmp configure reads stdin.
14019 Reported by Noah Misch.
14021 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
14023 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
14024 from /dev/null, as "configure" shouldn't read stdin, and this
14025 insulates us from problems (e.g., when testing for "cl").
14026 Suggested by Alexandre Duret-Lutz. Also, do this redirection
14027 before invoking "hostname" or "uname".
14028 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14029 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
14030 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
14031 "</dev/null" since it's now done at the top of 'configure'.
14032 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
14033 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
14034 Also, replace grep with shell pattern-matching, to save a process.

14038 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
14039 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
14040 avoid thinking that Allegro Common Lisp's "cl" command is a C++
14043 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
14045 * doc/autoconf.texi (Limitations of Usual Tools): Document that
14046 grep -q isn't portable. Improve grep -s explanation.
14047 Problem reported by Dan Manthey.

14054 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
14056 * doc/autoconf.texi: Use @acronym for DJGPP.
14057 Fix some @code's that should have been @env's, and vice versa.
14058 Sort environment variable names.
14059 Mention that shells no longer inherit IFS.
14060 Don't recommend PATH_SEPARATOR=';' so strongly.
14061 Mention that $RANDOM might expand to the empty string.
14062 "symlink" and "soft link" -> "symbolic link".
14063 Improve mktemp description (reported by Bruno Haible).

14202 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
14203 Update the long comment explaining it.
14205 m4_require no longer writes an ``is required by'' line to the
14206 execution stack. It contains only one bit of non-redundant
14207 information: that the macro was required, not called. And even
14208 this bit is useless in most situations: have you ever met a macro
14209 which both calls and requires the same macro?
14211 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
14212 (_m4_defun_pro_outer): ... only via this macro, for the outermost

14215 (m4_expansion_stack_pop): Remove the misplaced comment.
14216 (m4_require): Don't put the ``is required by'' line to the
14217 execution stack; slightly improve the out-of-a-defun error message.

14260 Warn about newline stripping in `` and $(). Update Solaris
14262 (Limitations of Builtins): Use expr "X...", not expr "x...", as

14631 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
14632 "char c = '\200';" rather than "char c = 0x80;" as the

14785 Remove ansi2knr.c; nobody uses it.
14786 (ansi2knr.c-url_prefix): Remove.
14787 (cvs-update): Fix test for failure. I don't know why it ever
14790 * doc/autoconf.texi: Update URLs, some of which went stale.
14791 Use @uref rather than @href.
14793 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
14794 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
14796 * config/config.guess, config/config.sub, config/elisp-comp,
14797 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
14798 doc/fdl.texi, doc/standards.texi: Sync with master copy.
14800 * NEWS, TODO, configure.ac, bin/autoscan.in,

14807 tests/tools.at, tests/torture.at:
14808 Use "file name" rather than "filename" or "path",
14809 to be consistent with the terminology of the GNU coding standards.
14811 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
14813 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
14814 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
14815 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
14816 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
14818 More fixes to support spaces in the name of the build directory.
14819 This isn't a complete fix but it's an improvement.
14821 * bin/autoconf.as (autom4te_options): New var.
14822 Use it instead of appending to AUTOM4TE, so that we can allow
14823 spaces in the build directory's absolute name.
14824 * bin/autoheader.in ($autoconf): Allow spaces in file names.
14825 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
14826 AT_CHECK_NOESCAPE): Likewise.
14827 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,

14838 * doc/autoconf.texi (Function Portability): Document isinf and
14839 and isnan. From a suggestion by Kevin Ryde.
14841 * lib/Autom4te/General.pm (END): Return correct exit status even
14842 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
14844 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
14846 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
14847 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
14848 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.

14856 * lib/autom4te.in (Automake-preselections): Preselect
14857 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
14859 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
14861 * lib/autom4te.in (Automake-preselections): Preselect
14862 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
14865 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
14867 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
14869 * doc/autoconf.texi (Shellology): Mention BIN_SH.
14870 Document problem with "`""`" in pdksh POSIX mode.
14872 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
14874 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
14875 with pdksh, too. Problem reported by Patrick Welche via
14877 * doc/autoconf.texi (Shellology): Note that set -o posix is
14878 useful for pkdsh, too.
14880 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
14882 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
14883 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
14884 Don't fail if ENV or BASH_ENV is readonly.
14885 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
14886 etc. are read only. Problem reported by Ludovic Courtes.
14888 2004-06-23 Noah Misch <noah@cs.caltech.edu>
14890 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
14891 zsh, disable GLOB_SUBST to avoid backslash handling problems.
14894 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
14896 * doc/autoconf.texi (File System Conventions): Warn about
14897 names like "aux". Problem reported by Eric Blake.
14899 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
14900 by zero instead of array size, so that we can use any arithmetic
14901 constant expression (instead of requiring an integer constant
14902 expression). This allows us to test expressions like DBL_MAX <
14903 LDBL_MAX, which didn't conform to the C standard using the old
14905 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
14906 now that we can do floating-point tests at compile time.
14908 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
14910 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
14911 and LDBL_EPSILON, as the resulting expression isn't an
14912 integer constant expression and violates the C standard.
14913 Problem reported by Nelson H. F. Beebe. Also, check
14914 for "L" suffix, and check that long double doesn't have
14915 worse range or precision than double, that mixed-mode
14916 arithmetic doesn't generate a diagnostic, that double
14917 constants fit in long double.
14919 2004-06-03 Kevin Ryde <user42@zip.com.au>
14921 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
14922 malloc(0) and realloc(NULL,size).
14924 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
14927 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
14929 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
14930 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
14933 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
14935 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
14936 can be rewritten using if-then-else. Suggested by Bruno Haible.
14938 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
14940 * doc/autoconf.texi (testsuite Scripts): Fix typo.
14941 Problem reported by Stepan Kasal.
14943 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
14945 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
14946 change). Patch reported by Ralf Wildenhues in
14947 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
14949 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
14950 function F exists if the compiler and linker let you compile an
14951 expression like (F != 0). Recent versions of GCC optimize away
14952 the reference to F in that case, since every function address must
14953 be nonzero, so the link succeeds even if F does not exist.
14954 Problem reported by Manu in
14955 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
14957 * doc/autoconf.texi (Systemology): Standardize on the spelling of
14958 "Unix". Many uses changed.
14959 (Limitations of Builtins): Explain better why the ! command isn't
14962 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
14964 * lib/autom4te.in (Automake-preselections): Preselect
14965 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.

14969 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
14970 referencing AC_FUNC_STRERROR_R.
14972 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
14973 note pessimistic assumption when cross compiling.
14975 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
14977 * doc/autoconf.texi (Limitations of Make): Note that BSD make
14978 (until 2004) invoked subcommands with sh -e, contra POSIX.
14979 Reported by Kevin Ryde.
14981 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
14983 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
14984 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
14985 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
14986 `test -f " /usr/bin/grep"', which _always_ failed.
14987 (AC_PROG_SED): Ditto bogus PATH fix.
14988 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
14989 requires that grep correctly supports _multiple_ `-e' options, rather
14990 than stating only that grep should accept `-e'.
14992 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
14994 Port to C99, which requires that 'exit' be declared.
14996 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
14997 to ensure that stdlib.h is included.
14998 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
14999 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
15000 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
15001 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
15002 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
15003 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
15004 when using 'exit' in a test; C99 requires that 'exit' be declared.
15006 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
15008 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
15009 now prefers 'grep' implementations that accept -e.
15010 (Limitations of Usual Tools): Describe problems of traditional
15011 egrep and fgrep with long input lines, and of traditional grep
15013 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
15014 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
15015 All callers changed. Append /usr/xpg4/bin to the PATH, for
15017 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
15018 the user with complaints about multiple -e options.
15019 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
15020 Define it with AC_PROG_GREP.
15021 * configure.ac (AC_PROG_GREP): Add.
15022 * lib/freeze.mk (GREP): New macro.
15024 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
15026 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
15027 a possible candidate only after all others fail, rather than
15028 consulting it first. This improves backward compatibility by
15029 better reflecting the way shell selection occurred in previous
15030 versions of Autoconf, and should help to avoid triggering latent
15031 problems in other packages, such as the one in Automake where zsh
15032 is not handled robustly:
15033 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
15034 Although it is not Autoconf's responsibility to work around
15035 problems in Automake, it nevertheless makes sense to avoid
15036 introducing unnecessary incompatibilites.
15038 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
15039 Gary V. Vaughan <gary@gnu.org>
15041 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
15042 how deeply nested we are when a suitable tool is found, set the
15043 ac_path_TOOL_found flag.
15044 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
15045 nested we are in this macro. Break out of all 3 nested loops if
15046 ac_path_TOOL_found is set.
15048 2004-04-21 Gary V. Vaughan <gary@gnu.org>
15050 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
15051 of the _AS_PATH_WALK loop too if GNU flavor is found.
15053 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
15055 * doc/autoconf.texi (Limitations of Make): Update documentation
15056 for `$<'. New entry `Long lines', based on a report from Simon
15057 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
15058 paragraph about DJGPP, based on a mail from Richard Dawe.
15060 2004-04-20 Paul Eggert <eggert@twinsun.com>
15062 * tests/c.at (C keywords): Don't assume that GCC supports
15063 "restrict" and "inline", as sufficiently-old GCC versions do not
15064 (also, GCC configured to be in pedantic C89 mode does not).
15065 Problem reported by Sumit Pandya in:
15066 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
15068 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
15069 consider -g to work if it generates warnings when plain compiles
15070 don't. Problem reported by Braden McDaniel in:
15071 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
15073 * doc/autoconf.texi (Slashes): New section, to document a problem
15074 reported by Jim Meyering in:
15075 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
15077 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
15078 linker output files before linking, to work around IRIX 6 linker bug.
15079 Problem reported by Rainer Orth in:
15080 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
15082 2004-04-20 Gary V. Vaughan <gary@gnu.org>
15084 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
15085 best tool so far counter rely on the tool path variable name to
15086 avoid checks for one tool being affected by the results of running
15087 the length check on a previous tool.
15089 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
15090 match expression argument, as different greps have different
15091 regular expression flavours.
15092 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
15094 (AC_PROG_EGREP): Pass 'EGREP$'.
15095 (AC_PROG_GREP): Pass 'GREP$'.
15097 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
15099 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
15100 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
15102 2004-03-29 Paul Eggert <eggert@twinsun.com>
15104 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
15105 Types, Specific Compiler Characteristics, System Services,
15106 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
15107 etc. consistently instead of 'long', 'short', 'unsigned' etc.
15108 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
15109 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):

15122 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
15123 now defines HAVE_DECL_TZNAME if it is declared, when
15124 HAVE_STRUCT_TM_TM_ZONE is not defined.
15125 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
15126 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
15129 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
15131 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
15132 superfluous backslashing of quotes (") in sed expressions;
15133 thanks to Paul Eggert.
15135 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
15137 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
15138 Fortran compiler is ifort, also added pghpf; thanks to Nelson
15139 H. F. Beebe for the bug report.
15141 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
15143 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for

15195 * bin/Makefile.am (edit): Don't use $< in a context where
15196 POSIX doesn't require support for it. Use $@.in instead.
15197 Problem reported by Anthony N. Frasso in
15198 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
15199 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
15201 2004-02-23 Gary V. Vaughan <gary@gnu.org>
15203 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
15204 from the next generation of Libtool.
15205 * lib/autom4te.in (Autoreconf-preselections): Ditto.
15207 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
15209 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
15210 is not always thread-safe. Report from Nathanael Nerode.
15212 2004-02-18 Paul Eggert <eggert@twinsun.com>
15214 Fix a dependencies problem, stemming from a Autoconf 2.59 build
15215 problem on QNX reported by Stephen Rasku in
15216 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
15218 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
15219 $(m4sh_m4f_dependencies); this removes a FIXME.
15220 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
15221 (MAINTAINERCLEANFILES): Split into pieces,
15222 one per related section. Add $(srcdir)/wrapper.in.
15224 2004-02-09 Paul Eggert <eggert@twinsun.com>
15226 * doc/autoconf.texi (Setting Output Variables): Emphasize that
15227 AC_SUBST provides no portable way to escape literal newlines.
15229 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
15230 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
15231 Darwin uses -lcrt2.o and there's little point to cataloging all
15232 the system variants. Partial fix reported by Andreas Waechter in:
15233 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

15247 refer to the correct file.
15248 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
15249 the behavior of the third argument.
15250 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
15251 correctly the behavior of the third argument. Document
15252 what the three macros that AU_DEFUN defines do. Fix
15253 warning message when the third argument includes $0

15257 Eric Sunshine <sunshine@sunshineco.com>
15258 Paul Eggert <eggert@twinsun.com>
15260 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
15261 (AS_INIT): Output shell initialization there. Removed optional
15262 parameter. Expand _AS_SHELL_FN_SPY.
15263 (AS_INIT_WITH_SHELL_FN): Removed.
15264 (_AS_SHELL_FN_SPY): New macro.
15265 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
15267 (AS_SHELL_SANITIZE): Remove loop to find better shell
15268 and documentation for the parameter.
15269 (_AS_DETECT_BETTER_SHELL): Move it here.

15271 (_AS_RUN): Move it here, support testing with eval.
15272 (AS_REQUIRE_SHELL_FN): Require shell functions when
15274 (_AS_LINENO_WORKS): Put around braces, we do not
15275 trigger the bash bug anymore.
15276 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
15277 use AS_INIT_WITH_SHELL_FN.
15278 * bin/autoconf.in, tests/wrapper.in: Regenerated.
15280 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
15282 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

15285 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
15286 (AU_DEFUN): Honor the third parameter, create autoupdate
15287 macros with AU_DEFINE.
15288 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
15289 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

15292 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

15297 * lib/autoconf/status.m4: Remove FIXME.
15298 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
15299 that the macro is not present anymore in the updated

15308 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
15309 2003 (except 1997) to the list of copyright years. This undoes
15310 the 2003-05-22 change, which removed the older years from the list.
15311 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
15313 2004-01-27 Gary V. Vaughan <gary@gnu.org>
15314 Albert Chin-A-Young <china@thewrittenword.com>
15316 * lib/autoconf/programs.m4 (AC_PROG_GREP): New macro to test for a
15317 grep or ggrep program in PATH that accepts as long lines as
15319 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
15321 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
15322 egrep and fgrep respectively if $GREP -E/-F don't work.
15323 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
15324 _AC_PROG_GREP, and AC_PROG_SED.
15325 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
15326 longest input length accepted by a command.
15327 (AC_PROG_SED): Use it.
15328 * doc/autoconf.texi (Particular Programs): Document the changes.
15331 2004-01-27 Paul Eggert <eggert@twinsun.com>
15333 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
15334 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
15335 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.

15355 2004-01-26 Paul Eggert <eggert@twinsun.com>
15357 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
15358 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
15359 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
15360 not <inttypes.h>. Problem reported by Tim Mooney in
15361 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
15362 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
15365 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
15366 otherwise "make check" fails because it forbids cmp (I guess
15367 because cmp treats files as binary on DOS-like systems).
15369 * tests/mktests.sh: Update copyright date to 2004, since some tests
15370 have changed in 2004.
15372 2004-01-23 Gary V. Vaughan <gary@gnu.org>
15374 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
15375 non-truncating sed or gsed program in PATH.
15376 * tests/acprograms.at: Add it.
15377 * doc/autoconf.texi (Particular Programs): Document it.
15380 2004-01-15 Paul Eggert <eggert@twinsun.com>
15382 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
15383 -std1 disables some useful extensions on Tru64. Problem reported
15384 by N. Lichtmaier in
15385 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
15387 2004-01-14 Paul Eggert <eggert@twinsun.com>
15389 * doc/autoconf.texi (Programming in M4sh): Document that
15390 AS_MKDIR_P succeeds if the destination is a symbolic link
15391 to an existing directory.
15392 (Limitations of Usual Tools): Note that mkdir -p might not
15393 succeed on symlinks to directories.
15395 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
15397 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
15398 * bin/autoheader.in: Grammar fix in message.
15399 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
15400 Test for dir before calling mkdir -p. (trivial changes)
15402 2004-01-13 Eric Blake <ebb9@byu.net>
15404 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
15405 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
15407 2004-01-10 Jim Meyering <jim@meyering.net>
15409 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
15411 2004-01-09 Paul Eggert <eggert@twinsun.com>
15413 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
15414 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
15415 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
15416 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
15417 AC_COMPILE_IFELSE, since we now assume our caller invokes
15418 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
15419 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
15420 of AC_RUN_IFELSE; this avoids the warning mentioned above.
15421 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
15423 2004-01-07 Paul Eggert <eggert@twinsun.com>
15425 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
15426 `"'...'"`, as it's confusing (and I suspect it may not work on
15427 some platforms). The code was incorrect anyway, as it assumed
15428 that \$ evaluated to itself in that context. Reported by
15429 Alexandre Duret-Lutz.
15431 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
15433 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
15434 and _LT_AC_TAGCONFIG.

15438 * doc/autoconf.texi (One Macro Call): Fix an incorrect
15439 example, and add more examples. Reported by Eric Sunshine.

15444 Remove warning against "rm -fr" introduced yesterday; it
15447 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
15448 autoscan, autoupdate, ifnames): Don't use chmod -w.
15449 * lib/Makefile.am (autom4te.cfg): Likewise.

15457 by doing lineno substitution only on lines containing "$LINENO".
15459 2004-01-04 Paul Eggert <eggert@twinsun.com>
15461 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
15462 Use "rm -f" to remove conftest.sed, not plain "rm".
15463 Bug reported by David Relson in
15464 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
15466 * Makefile.am (autom4te-update):
15467 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
15468 * Makefile.maint (my-distcheck, do-po-update): Likewise.

15481 2004-01-03 Paul Eggert <eggert@twinsun.com>
15483 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
15484 -c -o might not work. From a suggestion by Kevin Ryde.
15485 (C Compiler, Generating Sources, Limitations
15486 of Usual Tools, Limitations of Make, Making testsuite Scripts):
15487 Don't put '-o' after non-options, as POSIX doesn't allow this.
15488 Mention that cc's name might be gcc or c89 or whatever.
15490 2004-01-04 Kevin Ryde <user42@zip.com.au>
15492 * doc/autoconf.texi: Add various further index entries.
15494 2003-12-29 Paul Eggert <eggert@twinsun.com>
15496 * bin/autoreconf.in (autoreconf_current_directory):
15497 Fix typo: mkdir without umask arg.
15499 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
15501 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
15502 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
15503 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
15504 explanation clearer.
15506 2003-12-24 Andreas Schwab <schwab@suse.de>
15508 * doc/autoconf.texi (Default Includes): Fix misspelling of

15514 * configure: Regenerate.
15515 * tests/atlocal.in: Store the result here.
15516 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

15518 of explicitly testing.
15519 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
15520 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
15521 * tests/tools.at (Syntax of the shell scripts): Simplify
15522 using AT_CHECK_SHELL_SYNTAX.

15524 AT_CHECK_PERL_SYNTAX.

15591 parameter of AU_DEFUN.
15592 * lib/autoconf/autoupdate.m4 (AU_DEFINE): Remove.

15594 Use AC_DEFUN directly, not AU_DEFINE.
15595 * lib/autoconf/status.m4 (AC_LINK_FILES): Move the message into
15596 the expanded body, consistently with other macros such as AC_USG.
15598 2003-11-17 Paul Eggert <eggert@twinsun.com>
15600 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
15601 into the initial confdefs.h, to work around a bug in NextStep 3.3
15602 patch 3 reported by Eric Sunshine.
15604 2003-11-15 Kevin Ryde <user42@zip.com.au>
15606 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
15607 than $target since the latter is not usual, add guidelines on when to
15608 use or not use the system type.

15789 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

15814 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
15815 cache variable instead of $G77 to decide whether to include -O2,
15816 since $G77 is specific to Fortran 77.

15820 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
15821 free" flag. Re-order flags tested into rough order of popularity.
15823 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
15825 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
15826 arguments so that it can be used with syntax identical to
15827 AC_PROG_F77, and so that we can more easily decide to
15828 remove/deprecate the DIALECT optional argument in the future if it
15829 proves troublesome.
15830 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
15831 non-freeform-supporting compilers. Document freeform flags.
15833 2003-10-03 Akim Demaille <akim@epita.fr>

15895 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
15896 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
15897 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

15900 2003-09-26 Akim Demaille <akim@epita.fr>
15902 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
15903 directory for AC_CONFIG_COMMANDS' first argument exists.
15904 This makes valid the invocation of _AC_SRCPATH that follows.
15905 Reported by Eric Sunshine.

15929 The test suite are sometimes assigning timings incorrectly.
15930 Reported by Henk Krus.
15931 Diagnosed by Nicolas Joly.
15933 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
15935 Instead of making AT_help a sequence of assignments to grow
15936 $at_help_all, just make AT_help_all be the growing contents of
15937 $at_help_all, and make a single assignment in...
15939 (at_times_skip): Flip the meaning and rename as...
15940 (at_times_p): this.

15951 (ifnames): chmod -w.
15952 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
15953 executables, not bin/ executables! Otherwise all the magic needed
15954 to find non installed files is turned off. This caused a failure
15955 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
15956 as found in its environment (sent by tests/autoreconf): pointing
15957 to bin/autom4te that could not find its files.
15958 * tests/mktests.sh: Force the replacement of generated files, for
15959 the sake of "mv" program that are interactive when overwriting a

16054 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
16056 Add support for newer Fortran dialects. The F77 interface is
16057 unchanged, and continues to support Fortran 77. New FC macros
16058 correspond to all the old F77 macros, with output variables FC,
16059 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
16060 available dialect, but older dialects can be specified. There are
16061 new macros AC_FC_SRCEXT to set the source extension, and
16062 AC_FC_FREEFORM to accept free-form source files.

16149 (local-checks-available): this.
16150 (local-check): New.
16152 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
16153 * configure.ac: Require Automake 1.7.6.
16155 2003-08-22 Akim Demaille <akim@epita.fr>
16157 Output stack traces in warnings.
16159 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
16160 Replace the former...
16161 (m4_warn): Pass the call stack to _m4_warn.
16162 * bin/autom4te.in: Adjust to output the call stack.
16163 * tests/m4sugar.at (m4@&t@_warn): Adjust.
16165 2003-08-22 Akim Demaille <akim@epita.fr>
16167 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
16168 * bin/autom4te.in: Adjust.
16170 2003-08-21 Akim Demaille <akim@epita.fr>
16172 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
16173 (&verbose): Remove.
16174 (&getopt): Adjust the note and verb channels, depending upon
16176 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
16177 * bin/autoupdate.in: Adjust.
16178 Use &verb, not &verbose.
16180 2003-08-21 Akim Demaille <akim@epita.fr>
16182 * bin/autoheader.in (&parse_args): Use &parse_warnings and
16184 ($help): Use Autom4te::ChannelDefs::usage.
16185 * bin/autoscan.in: Use Autom4te::ChannelDefs.
16186 * lib/Autom4te/General.pm: Don't export error: you don't own it.
16188 2003-08-21 Akim Demaille <akim@epita.fr>
16190 First stab at preserving warnings between calls to autom4te,
16191 including when the cache is used.
16193 There are still several issues: (i) there are too many runs of m4
16194 (one for include, one for warnings, and some more), (ii) warnings
16195 spreading on several lines are not handled gracefully, (iii) the
16196 code meant to have the call stack display for errors does not work
16197 (its handling should move from m4 to autom4te).
16199 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
16201 (@preselect): Add m4_warn.
16202 ($exit_status): Remove, use $exit_code.
16203 ($help): Use Autom4te::ChannelDefs::usage.
16204 (&handle_m4): No longer define the m4_warnings.
16205 At each run, extract and report the warnings.
16206 Always cache the result, including if the exit status is on
16207 failure, since if nothing changes, we should result in the same
16208 failure, hence we can use the cache.
16209 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
16210 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
16212 (m4_warn): Redefine as a do-nothing: it is its invocation that
16213 matters, as warnings are now reported via traces.
16214 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
16215 the contents of m4_warn: make it _call_ m4_warn, so that tracing
16216 the latter reveals calls to the former.
16220 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

16242 (&catfile): Remove.
16243 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
16244 * bin/autoscan.in: Adjust.
16246 2003-08-20 Akim Demaille <akim@epita.fr>
16248 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
16249 Reported by Alexandre Duret-Lutz.
16251 2003-08-20 Akim Demaille <akim@epita.fr>
16253 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
16254 * bin/autom4te: Adjust.
16255 In particular, be Autoconf tools are really silent when properly
16256 working, bind the verbosity of the 'note' channel to $verbose.
16257 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
16258 (&xsystem, &contents): Remove, since they are exported by...
16259 * lib/Autom4te/FileUtils.pm: this.
16261 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
16262 * lib/Autom4te/FileUtils.pm: here.

16320 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
16321 shorter column three. Add DESCRIPTION to log file content.
16323 2003-08-13 Derek Price <derek@ximbiot.com>
16325 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

16377 From Gareth McCaughan.
16379 2003-06-23 Akim Demaille <akim@epita.fr>
16381 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
16382 not all of them. This fixes 1. the fact that when testing
16383 Autoconf there are many many config.log, 2. the incorrect use of
16384 top_srcdir to find config.log.
16385 Don't mix the detailed output of failed test with the summary of
16386 failures. Rather, append detailed log afterwards.
16388 2003-06-23 Akim Demaille <akim@epita.fr>
16390 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
16391 always run: output config.log on $at_group_log.
16393 2003-06-23 Akim Demaille <akim@epita.fr>
16395 * tests/torture.at (#define header templates): Don't use quotes in

16469 (handle_exec_errors): New function. Work around $! being
16470 altered by WEXITSTATUS.
16471 (xqx, xsystem): Use handle_exec_errors.
16473 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
16475 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
16476 Do not call `_exit()', simply modify `$?'.
16477 (xsystem): Reset $! before running system, and check it afterward.
16478 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
16479 63 for version mismatches.
16481 2003-05-23 Akim Demaille <akim@epita.fr>
16483 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
16484 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
16485 the middle of a line).

16503 Paul Eggert <eggert@twinsun.com>
16505 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
16506 Remove `#include <stdlib.h>' from the list; we should never
16507 make confdefs.h include <stdlib.h> or <cstdlib>, because the
16508 resulting namespace pollution would cause other tests to fail.
16509 Configure scripts run with some older versions of g++ and HP's
16510 aCC would fail due to such an #include. Problems reported by
16511 Matthew Mueller in <http://bugs.debian.org/120704> and by
16513 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
16514 In the test, use the test declaration before including <stdlib.h>,
16515 as that's closer to how it'll be used.
16517 2003-05-23 Akim Demaille <akim@epita.fr>
16519 * doc/autoconf.texi (Header Portability): ucred.h.
16522 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
16524 Overhaul Autotest's logging: generate separate log files
16525 in testsuite.dir/NNN/testsuite.log, and append them to
16526 testsuite.log instead of re-running the test verbosely.
16528 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
16529 file descriptor, write 0 to at_status_file instead of setting
16530 at_status=0, initialize some new variables (at_status_file,
16531 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
16532 to rerun the tests, instead append the at_group_log to the
16533 at_suite_log when a test fails.
16534 (AT_SETUP): pipe the test case's output into at_tee_pipe,
16535 with the AS_MESSAGE_LOG_FD redirected to stdout.
16536 (AT_CLEANUP): save the output status in $at_status_file
16537 and restore it, redirect the AS_MESSAGE_LOG_FD back to
16538 its original place.
16539 (AT_CHECK): since tests are run with a redirected stdout,
16540 and used to be re-run in verbose mode, turn some $at_verbose
16541 into echo, and don't redirect the output of testing stdout
16544 * lib/autotest/autoconf.texi (testsuite Scripts): Update

16665 2003-05-06 Akim Demaille <akim@epita.fr>
16667 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
16668 longer updates aclocal.m4 if useless, (ii) if a file m4_included
16669 by aclocal.m4 is changed it might require the importing of another
16670 m4 extension file, i.e., aclocal must be run.
16672 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
16673 (&parse_args): Use --force with aclocal if required and supported.

16687 2003-04-29 Derek Price <derek@ximbiot.com>
16689 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
16690 seperator with m4_append_uniq(). It doesn't work.
16691 (AT_CLEANUP): Add `;' to end of at_help_all.
16692 (AT_INIT): Allow --keywords to be specified more than once. When
16693 grepping $at_help_all for keywords, use the field and keyword

16699 * doc/autoconf.texi: Make the dir entries in the autoconf manual
16700 align better with others. I also made some of the individual
16701 entries on one line, for brevity and to make it easier for me to

16773 * tests/torture.at (Configuring subdirectories): Require aclocal
16774 1.4, otherwise the test fails, as it does support configure.ac.

16798 obsolete AC_HELP_STRING.
16799 (AC_HELP_STRING): AU_DEFUN to...

16863 * bin/ifnames.in: Add final newline to help and version messages.
16865 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
16866 to cope with DOS-style absolute paths, when constructing
16869 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
16870 When constructing paths with IFS=:, quote the path. If we're
16871 constructing a DOS-style absolute path, we don't want to split it
16874 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
16877 2003-02-25 Pavel Roskin <proski@gnu.org>

16889 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,

16894 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
16895 format starting with "-".
16897 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
16899 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
16900 is not portable inside Makefile.
16902 2003-02-20 Akim Demaille <akim@epita.fr>
16904 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
16905 compiler says yeah, but preproc says nope, compiler is right.
16906 Conversely, prompt the reader to send a bug report to the
16907 maintainers of the package, not of Autoconf.

16911 * bin/autoreconf.in (autoreconf_current_directory): Properly
16912 handle an empty aclocal.m4.

16917 $ac_prefix_program.
16920 2002-12-23 Paul Eggert <eggert@twinsun.com>
16922 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
16923 innocuous variant befor including <limits.h> or <assert.h>. This
16924 works around a bug reported by Albert Chin: HP-UX 11i
16925 (and earlier versions) have a <limits.h> that declares
16926 gettimeofday and many other functions.
16928 2002-12-03 Paul Eggert <eggert@twinsun.com>
16932 * NEWS, configure.ac: Update version.
16934 * doc/fdl.texi: Upgrade to FDL version 1.2.
16936 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
16937 nontrivially in main's body, so that f's external declaration is
16938 not optimized away in AIX. This should fix the bug reported by
16940 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
16942 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
16943 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
16944 defined, to support freestanding compilers. This should fix the
16945 bug reported by Momchil Velkov in
16946 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
16948 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
16949 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

16960 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
16961 \(.*\) match is too long and there is something more to be checked.
16962 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

16980 Update from masters.
16982 2002-11-14 Akim Demaille <akim@epita.fr>
16984 * Makefile.maint: Sync with Bison, i.e.:
16985 (po-check): Scan .l and .y files instead of the
16986 .c and the .h files that they generate. This fixes the bug
16987 reported by Tim Van Holder in:
16988 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
16989 Look for N_ as well as for _. Try to avoid matching #define for
16993 2002-11-14 Akim Demaille <akim@epita.fr>
16995 * doc/autoconf.texi (C Compiler): Compiling several files at once.
16996 From Paul Eggert and Albert Chin-A-Young.
16998 2002-11-14 Akim Demaille <akim@epita.fr>
17000 * doc/autoconf.texi (C Compiler): Solitary backslashes.
17001 From Paul Eggert and Albert Chin-A-Young.
17003 2002-11-14 Kevin Ryde <user42@zip.com.au>
17005 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
17006 than assigning in main, to avoid HP cc +O3 optimizing it away.
17008 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
17010 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
17011 option. Process --recheck after parsing all options. Pass -q
17012 option to configure on --recheck.
17013 (AC_OUTPUT): Pass -q from configure to config.status.
17014 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
17015 arguments to record.
17016 * doc/autoconf.texi (config.status Invocation): Document
17017 config.status -q option.
17019 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
17021 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
17022 Makefile.in if Makefile.am exists.
17023 (output): Strip `.am' from Makefiles. Don't
17024 output AC_CONFIG_FILES if no Makefiles were found.
17026 2002-11-07 Akim Demaille <akim@epita.fr>
17028 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
17029 (local_updates): New.
17030 * Makefile.maint: Update, from CVS Bison.
17031 (local_updates): New.
17033 2002-11-06 Akim Demaille <akim@epita.fr>
17035 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
17036 declaration in extern "C" too.
17037 Reported by Roberto Bagnara.
17039 2002-11-06 Akim Demaille <akim@epita.fr>

17043 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
17044 Reported by Ezra Peisach.
17046 2002-11-05 Akim Demaille <akim@epita.fr>
17048 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
17050 We _have_ to stop using the old compatibility scheme that tried to
17051 avoid useless backslashes because Libtool 1.4.3 contains a
17052 AC_DEFINE([error_t], [int],
17053 [Define to a type to use for \`error_t' if it is not
17054 otherwise available.])
17055 We _have_ to quote the single quote and backslashes with \. The
17056 old compatibility scheme saw that ` was backslashed, and therefore
17057 did not quote the single quote. Hence before this patch, Autoconf
17058 was not compatible with Libtool.
17060 2002-11-04 Paul Eggert <eggert@twinsun.com>
17062 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

17079 (&autoreconf): here.
17080 ($help, $make, &parse_args, &autoreconf_current_directory):
17082 * doc/autoconf.texi (autoreconf Invocation): Adjust.
17084 2002-10-31 Bruno Haible <bruno@clisp.org>
17086 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.
17087 Change name of cache variable to ac_cv_func_malloc_0_nonnull.
17088 (AC_FUNC_MALLOC): Change description of HAVE_MALLOC macro.

17449 Reported by Alexandre Duret-Lutz.
17451 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

17456 (&up_to_date): If a file that was included according to the cache

17471 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
17472 if some file was changed instead of `print'.
17473 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

17507 file name to enable parallel executions.
17508 From Sam Varshavchik.
17510 2002-10-08 Akim Demaille <akim@epita.fr>
17512 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
17513 aclocal invocation, as Gettext macros might not be visible to
17515 Instead of blindly running autopoint, scan configure.ac (not the
17516 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
17517 Reported by Paul D. Smith.
17519 2002-10-08 Paul Eggert <eggert@twinsun.com>
17521 Work around problems found when POSIXLY_CORRECT=1 is set.
17522 None of this seems to have anything to do with POSIX, really,
17523 but it's how Perl getopt works.
17524 * bin/autom4te.in (parse_args): Configure GetOpt with
17526 * doc/autoconf.texi (Invoking autom4te):
17527 --warning -> --warnings.

17549 * tests/torture.at (Configuring subdirectories): Be robust to
17550 users who use config.site to require for a cache: in this case,
17551 the two last configure runs, using two different sets of
17552 arguments, trigger a legitimate error.
17554 2002-09-28 Akim Demaille <akim@epita.fr>

17589 tests/autom4te itself.
17590 * lib/autoscan/Makefile.am: Include freeze.mk.
17591 (autoscan.list): New target --this file is no longer a source.
17592 (autoscan.pre): New file.
17594 2002-09-28 Akim Demaille <akim@epita.fr>
17596 * bin/autoscan.in (@kinds): Make them singular.
17598 (&init_tables): When --debug, report the list of rules to ease
17599 tracking changes in autoscan.list.
17600 * lib/autoscan/autoscan.list (function): Strip comments, sort.

17608 * bin/autoscan.in (&init_tables): Adjust.
17610 2002-09-28 Akim Demaille <akim@epita.fr>
17612 * lib/autoscan/functions, lib/autoscan/headers,
17613 * lib/autoscan/identifiers, lib/autoscan/makevars,
17614 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
17615 `functions' line is now prefixed with `function:'.
17616 * bin/autoscan.in (&init_tables): Adjust.
17618 2002-09-28 Akim Demaille <akim@epita.fr>
17620 From now on, autoscan files must always map a macro name to a
17621 word: there is no `default' macro for autoscan.
17623 * bin/autoscan.in (&init_tables): Reject entries with no macro at
17625 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
17628 2002-09-28 Akim Demaille <akim@epita.fr>
17630 * bin/autoscan.in (%c_keywords): Remove.
17631 (&used): Keep only track of the words we might be interested in.
17632 (&output_kind): It is no longer needed to look for non active
17635 2002-09-27 Akim Demaille <akim@epita.fr>

17646 Thanks to Bill Moseley and Paul Eggert.
17647 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
17648 the tmpdir must be created.
17649 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
17650 dir be in the build tree, instead of $TMPDIR.
17652 2002-09-27 Akim Demaille <akim@epita.fr>
17654 * bin/autoscan.in: Improve the comments.
17655 (&parse_args): Drop obsolete undocumented options.

17663 Reported by Ralf Corsepius.
17664 * doc/autoconf.texi (autoreconf Invocation): Likewise.
17666 2002-09-26 Akim Demaille <akim@epita.fr>
17668 Single suffix rules and seperated dependencies are not portable.
17670 * doc/autoconf.texi (Installation Directory Variables): Update.
17671 (Limitations of Make): Some about `Single Suffix Rules and
17672 Separated Dependencies'.
17673 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17674 (ifnames, autoscan, autom4te): Un-factor into several rules.
17676 2002-09-25 Paul Eggert <eggert@twinsun.com>
17678 * BUGS (Interoperability bugs): New section. Mention libtool
17679 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
17681 2002-09-24 Paul Eggert <eggert@twinsun.com>
17683 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
17684 make handles suffix-rules differently from GNU make.
17686 * bin/Makefile.am (SUFFIXES, .in): Remove.
17687 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
17688 Move the body of the old .in rule here.
17690 2002-09-16 Akim Demaille <akim@epita.fr>
17692 i960 compilers create `b.out' files by default.
17693 Reported by Ralf Corsepius.
17695 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
17696 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
17698 2002-09-13 Paul Eggert <eggert@twinsun.com>
17700 * doc/autoconf.texi (Particular Headers): Remove obsolete
17701 reference to `struct timezone' in the description of
17704 2002-09-13 Akim Demaille <akim@epita.fr>
17708 * config/config.sub, config/config.guess: Update.
17709 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
17710 * Makefile.am: Adjust.
17712 2002-09-13 Akim Demaille <akim@epita.fr>
17714 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
17715 reading config.log when the compiler is rejected.
17716 Suggested by Guido Draheim.
17718 2002-09-13 Akim Demaille <akim@epita.fr>
17720 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
17721 (chdir_init) might hang when stat'ing mounted directories.
17722 Reported by Vance Shipley.
17724 2002-09-12 Akim Demaille <akim@epita.fr>
17726 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
17729 2002-09-12 Akim Demaille <akim@epita.fr>
17731 * doc/autoconf.texi (Defining Symbols): Present two different
17732 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
17733 difference between 1 argument calls, and 2-3 argument calls.
17735 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
17737 * doc/autoconf.texi: Review grammar and punctuation.
17739 2002-09-11 Paul Eggert <eggert@twinsun.com>
17741 * doc/autoconf.texi: Fix minor formatting, spelling, and
17743 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
17744 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
17747 2002-09-11 Akim Demaille <akim@epita.fr>
17749 * doc/autoconf.texi (Questions): Rename as...
17751 (Defining Directories): New.
17753 2002-09-09 Akim Demaille <akim@epita.fr>
17755 * doc/autoconf.texi (Making testsuite Scripts): Update.
17756 Suggested by Nishio Futoshi.
17758 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
17760 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
17761 plain `@' is wanted.
17763 2002-09-09 Akim Demaille <akim@epita.fr>
17765 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
17766 `duplicates', since the algorithm was too naive and could keep
17767 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
17768 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
17769 Reported by Ralf Corsepius.
17770 * tests/torture.at (Configuring subdirectories): Exercise these
17773 2002-09-09 Akim Demaille <akim@epita.fr>
17775 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
17776 looking for a replacement file.
17777 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
17778 directory is relative.
17779 * doc/autoconf.texi (Generic Functions): Clarify the replacement
17780 directory definition.
17781 Reported by Andreas Schwab and Jim Meyering.
17783 2002-09-06 Akim Demaille <akim@epita.fr>
17785 * doc/autoconf.texi (Setting Output Variables): Clarify what
17786 precious variables are.
17787 Suggested by Pontus Skoeld.
17789 2002-09-05 Akim Demaille <akim@epita.fr>
17791 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
17792 (ifnames, autoscan, autom4te): Since we don't only depend on
17793 configure.ac variables (such as VERSION etc.), but also on prefix
17794 and so forth, depend on Makefile, not configure.ac.
17795 Reported by Alexandre Duret-Lutz.
17796 * doc/autoconf.texi (Installation Directory Variables): Adjust.
17798 2002-09-05 Kevin Ryde <user42@zip.com.au>
17800 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
17801 doesn't seem to be confined to ia64, just say "some versions".
17803 2002-09-04 Akim Demaille <akim@epita.fr>
17805 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
17807 * Makefile.am (maintainer-clean-local): Remove.
17808 (MAINTAINERCLEANFILES): Remove COPYING.
17810 2002-09-03 Paul Eggert <eggert@twinsun.com>
17812 * doc/autoconf.texi (Configuration Commands): Remove obsolete
17813 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
17816 2002-09-03 Akim Demaille <akim@epita.fr>
17818 * configure.ac: Bump to 2.53d.
17819 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
17820 as of today, on Automake's team suggestion.
17822 2002-09-03 Akim Demaille <akim@epita.fr>
17826 2002-09-02 Akim Demaille <akim@epita.fr>
17828 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
17830 * configure.ac: Disable SITE_MACRO_DIR.
17832 2002-09-02 Jim Meyering <meyering@lucent.com>
17834 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
17835 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
17836 Also, tweak grammar: s/make sure to/be sure to/.
17838 2002-09-02 Paul Eggert <eggert@twinsun.com>
17840 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
17841 directory names are generally preferable to physical names.
17843 2002-09-02 Akim Demaille <akim@epita.fr>
17845 * lib/Autom4te/General.pm (&update_file): s/die/error/.
17846 Reported by Raja R. Harinath.
17847 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
17848 * bin/autoupdate.in: Use error instead of die.
17850 2002-09-01 Paul Eggert <eggert@twinsun.com>
17852 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
17853 ordinary shell concatenation rather than echo+tr+sed command that
17854 runs afoul of a long-line-related sed bug in Solaris 8.
17856 * bin/autoheader.in (parse_args): --warning -> --warnings.
17858 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
17859 stdout, as traditional "ls" does.
17860 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
17861 _AC_COMPILER_EXEEXT_O): Likewise.
17862 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
17864 * bin/autoconf.as: Add --prepend-include option. This patch was
17865 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
17866 but bin/autoconf.in is generated automatically from bin/autoconf.as.
17868 * bin/autoconf.in, configure: Regenerate.
17870 * doc/autoconf.texi (Special Shell Variables): Mention
17871 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
17873 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
17874 MAILPATH and set PS1, PS2, PS4 to default values, to work
17875 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
17876 For LC_ALL etc, first try to set to "C" as POSIX requires and as
17877 the Autoconf documentation specifies; fall back to "unset" only if
17878 this fails. Use a shell for-loop for this rather than an m4 loop,
17879 to shorten the output script.
17881 2002-08-30 Paul Eggert <eggert@twinsun.com>
17883 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
17884 1003.1-2001's requirements for CDPATH. Give a simpler workaround
17885 for the CDPATH problem. Document PWD.
17886 (Limitations of Builtins): Document the problem that "cd $foo" and
17887 "ls $foo" may refer to different directories in shells conforming
17888 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
17889 example, since the old example is now out of date.
17891 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
17892 FOO" and "ls FOO" talk about different directories; this catches
17893 problems when POSIX 1003.1-2001 "cd" fails due to symlink
17896 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
17897 of rolling our own unset.
17898 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
17899 in practice we needn't worry about CDPATH if unset doesn't work.
17901 * Makefile.in, aclocal.m4, bin/Makefile.in,
17902 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
17903 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
17904 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
17905 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
17906 tests/Makefile.in: Regenerate with Automake 1.6.3.
17908 * config/config.guess, config/config.sub, config/mkinstalldirs:
17911 * configure: Regenerate with self.
17913 2002-08-30 Kevin Ryde <user42@zip.com.au>
17915 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
17918 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
17920 * bin/autom4te.in (Request::load): Correctly test for "do" read
17923 2002-08-29 Akim Demaille <akim@epita.fr>
17925 * lib/Autom4te/General.pm (&xqx): New.
17926 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
17927 hand, which is not portable.
17929 * bin/autom4te.in: Use them.
17930 Use &error instead of die.
17931 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
17934 2002-08-17 Paul Eggert <eggert@twinsun.com>
17936 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
17937 default list of compilers to try, since it was long ago superseded
17938 by the ksh fc builtin. Suggested by Steven G. Johnson.
17940 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
17942 * doc/autoconf.texi (Invoking autom4te): End the option table,
17943 fixing a bug introduced by the previous patch.
17944 (Limitations of Make): Add a 'target lookup' subentry in the
17945 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
17947 2002-07-29 Mark D. Roth <roth@feep.net>
17949 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
17950 options and use $AUTOM4TE_PATH.
17951 * doc/autoconf.texi: Remove documentation of autom4te
17952 --include-envvar and --site-macro-subdir options and document
17953 use of $AUTOM4TE_PATH.
17954 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
17955 arguments from each language section.
17957 2002-07-29 Paul Eggert <eggert@twinsun.com>
17959 * doc/install.texi: Include copyright symbol in copyright notice.
17961 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
17963 (AM_MAKEINFOFLAGS): New macro.
17964 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
17965 * Makefile.am (INSTALL): Use the new macros.
17966 Use -o rather than --output, since "missing" does not grok --output.
17968 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
17970 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
17971 comments do not always work. Never trust the exit status of
17974 2002-07-24 Kevin Ryde <user42@zip.com.au>
17976 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
17977 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
17979 2002-07-23 Paul Eggert <eggert@twinsun.com>
17981 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
17982 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
17983 apparently treats PATH="nonexistent" as if it contained ".".
17984 Bug reported by Stefan `Sec' Zehl.
17986 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
17988 * doc/autoconf.texi (Limitations of Make): Mention the special
17989 handling of the obj/ directory by BSD make.
17991 2002-07-20 Kevin Ryde <user42@zip.com.au>

18033 2002-07-17 Andreas Buening <andreas.buening@nexgo.de>
18035 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
18036 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
18037 latter was not run.
18039 2002-07-17 Akim Demaille <akim@epita.fr>
18041 * lib/Autom4te/General.pm (find_file): Browse the directories in
18042 the order they are given.

18062 macro directory, remove note that include path directories are

18254 This improves on an earlier suggestion by H. Peter Anvin.
18256 2002-05-16 Paul Eggert <eggert@twinsun.com>
18258 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
18259 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
18260 Both macros now accept an optional source-dir arg.
18261 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
18263 * NEWS: Document this.
18264 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
18266 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
18267 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
18268 not for GNU extensions; this undoes part of the 2000-11-03 change,
18269 reverting to 2.13-compatible behavior.

18277 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
18278 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
18279 and it causes a 'test' syntax error if it fails.
18280 Bug reported by Stephen Gildea.
18282 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
18283 If prototypes are supported, use them to check this at compile-time,
18284 instead of trying to check it at run-time. If we must do a run-time
18285 check, assume that setvbuf is standard when cross-compiling, as
18286 nonstandard setvbuf occurs only on ancient and unlikely hosts.
18287 Bug reported by Paul D. Smith.
18289 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
18290 argument specifying location of getloadavg.c. This removes a
18291 FIXME. This idea was taken from Jim Meyering's implementation in
18293 * doc/autoconf.texi (Particular Functions): Document this.
18294 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
18295 that's what the code does; this fixes a bug reported by
18298 2002-05-03 Akim Demaille <akim@epita.fr>
18300 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
18301 autopoint instead of gettextize.
18302 ($uses_alocal): Rename as...
18303 ($uses_aclocal): this.
18304 * doc/autoconf.texi (autoreconf Invocation): Adjust.
18305 Suggested by Bruno Haible.
18307 2002-05-03 Akim Demaille <akim@epita.fr>
18309 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
18311 2002-04-29 Paul Eggert <eggert@twinsun.com>
18313 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
18314 files to be 1 second older; just set them to be the same time.
18315 Also, sleep 1 second after the first aclocal, to work around
18316 problems with sub-second time stamps on the input files.
18318 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
18320 * doc/autoconf.texi: Mention "set -e -x" lossage
18321 under node "Limitations of Builtins".

18327 From Christian Cornelssen.
18329 2002-04-29 Akim Demaille <akim@epita.fr>
18331 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
18332 of lack of $LINENO support, then the test will compare the $LINENO
18333 in testsuite vs. the lineno in the test file. This is wrong, of
18335 Be sure to protect it.
18336 Reported by Patrick Welche.
18338 2002-04-25 Akim Demaille <akim@epita.fr>
18340 * doc/autoconf.texi (Obsolete Macros): Typo.
18341 Reported by Vladimir Volovich.
18343 2002-04-25 Akim Demaille <akim@epita.fr>
18345 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
18346 than some of the input files, hence, on the second run of aclocal,
18347 if some of its input are younger, make them older.
18348 Suggested by Paul Eggert.
18350 2002-04-25 Akim Demaille <akim@epita.fr>
18352 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

18357 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
18358 and ac_subst_vars be sh variables containing the list of
18359 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
18361 (_AC_INIT_PREPARE): Use them to log them.
18362 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
18363 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
18364 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
18365 _AC_SUBST_FILES and _AC_SUBST_VARS.
18366 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
18368 2002-04-24 Akim Demaille <akim@epita.fr>
18370 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
18371 autoheader, so that automake does not complain about a missing
18372 config.h.in that was to be created.
18374 2002-04-23 Akim Demaille <akim@epita.fr>

18566 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
18568 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
18569 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
18570 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
18571 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
18572 (AC_C_CONST): Same.
18573 (AC_C_INLINE): Same.
18574 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
18575 * doc/autoconf.texi, NEWS: Document.
18576 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
18579 2002-04-02 Akim Demaille <akim@epita.fr>
18581 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
18582 _AS_MKDIR_P_PREPARE.
18584 2002-03-28 Kevin Ryde <user42@zip.com.au>
18586 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
18587 to avoid versions of HP C which don't allow that.
18589 2002-03-27 Paul Eggert <eggert@twinsun.com>
18591 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
18592 (AS_SHELL_SANITIZE): Invoke it.
18593 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
18595 2002-03-26 Akim Demaille <akim@epita.fr>
18597 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
18599 2002-03-26 Akim Demaille <akim@epita.fr>
18601 * doc/autoconf.texi (Introduction): The GNATS base moved.
18603 2002-03-25 Paul Eggert <eggert@twinsun.com>
18605 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
18606 as POSIX requires, as it doesn't work with Zsh.
18607 * doc/autoconf.texi (Assignments): Document the problem.
18609 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
18611 * doc/autoconf.texi (Limitations of Make): Mention more issue
18612 about VPATH, overriding of macros in sub-makes, and handling of
18615 2002-03-21 Paul Eggert <eggert@twinsun.com>
18617 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
18618 problem with here-document buffer boundaries.
18620 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
18621 when reinvoking the shell, to work around problems with installers
18622 who put strange things like "cd" commands in their environments.
18624 2002-03-19 Akim Demaille <akim@epita.fr>
18626 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
18629 2002-03-19 Akim Demaille <akim@epita.fr>
18631 * bin/autoscan.in (scan_file): Specify the location in `&used'
18635 2002-03-19 Akim Demaille <akim@epita.fr>
18637 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
18638 From Nishio Futoshi.
18640 2002-03-19 Akim Demaille <akim@epita.fr>
18642 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
18644 2002-03-18 Paul Eggert <eggert@twinsun.com>
18646 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
18647 (Limitations of Usual Tools): Add mkdir section.
18649 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
18650 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
18651 back on AS_DIRNAME to compute prefixes otherwise; this is
18652 roughly what mkinstalldirs does. That way, we need not have
18653 our own filename disassembler. The old disassembler did not
18654 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
18656 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
18657 Create at_test_all by a series of assignments,
18658 not by a single assignment of a long string. The latter causes ksh
18659 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
18660 presumably because of a buffer overrun.
18662 2002-03-14 Paul Eggert <eggert@twinsun.com>
18664 * lib/autotest/general.m4 (at_times_skip):
18665 Renamed from at_times. Now a boolean.
18666 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
18667 says 'times: not found'.
18669 2002-03-14 Akim Demaille <akim@epita.fr>
18671 * bin/autoreconf.in (&study_gettextize): New.
18672 (&autoreconf): Handle newest gettextize.
18673 Rerun aclocal if needed.
18674 Suggested by Andreas Schwab.
18676 2002-03-13 Akim Demaille <akim@epita.fr>
18678 * doc/autoconf.texi (Special Shell Variables): More about IFS.

18682 * doc/autoconf.texi (Header Portability): New.
18683 Add information about stdint.h and inttypes.h from Paul Eggert.
18685 2002-03-13 Akim Demaille <akim@epita.fr>

18691 2002-03-12 Akim Demaille <akim@epita.fr>
18693 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
18696 2002-03-11 Andreas Schwab <schwab@suse.de>
18698 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
18699 does not do it if --with-lispdir is given.

18708 subdirectory should exist.
18710 2002-03-08 Akim Demaille <akim@epita.fr>
18712 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
18714 2002-03-08 Akim Demaille <akim@epita.fr>
18716 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
18717 aliases the actual variables, and modifications of the former
18720 2002-03-08 Akim Demaille <akim@epita.fr>
18722 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
18723 because of C-c: have m4 output in tmp files, then mv them.
18725 2002-03-08 Akim Demaille <akim@epita.fr>
18727 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
18728 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
18729 * bin/ifnames.in: Copyright update.

18744 2002-03-04 Akim Demaille <akim@epita.fr>
18746 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
18747 * lib/autoconf/general.m4 (AC_INIT): More informative error
18748 message for LIBOBJ.
18750 2002-03-04 Akim Demaille <akim@epita.fr>
18752 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
18755 2002-03-04 Akim Demaille <akim@epita.fr>
18757 * doc/autoconf.texi (Transforming Names): Equality between target
18758 and host is irrelevant.
18759 (Specifying Names, Canonicalizing): Remove all references to the
18760 backward compatibility hooks. Rather, collect them all into...
18761 (Hosts and Cross-Compilation): this new section.
18762 * doc/install.texi (System Type): Ditto.
18763 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
18764 that `--host' implies cross-compilation.
18766 2002-03-04 Akim Demaille <akim@epita.fr>
18768 * doc/autoconf.texi (Evaluation Macros): New.
18769 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
18771 (_m4_foreach): Define the variant with immediate evaluation so
18772 that it contains exactly the items, not an expression which
18773 evaluation is the current item.
18774 (m4_re_string, m4_re_word): Don't over quote them.
18776 2002-03-04 Akim Demaille <akim@epita.fr>
18778 Instead of having stacking `shift's evaluated at the end, let
18779 `foreach' loops immediately evaluate them.
18781 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
18782 $*. This is the n-th time I change my mind, but hopefully this is
18785 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
18787 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
18788 it was only a hack for m4_text_wrap.
18789 (m4_car2): Remove, replaced by...
18791 (_m4_foreach): Adjust.
18792 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
18793 m4_bpatsubst for clarification.

18845 AC_PREFIX_PROGRAM fails with dashed program names
18847 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh

18859 case/esac, some shells don't support it.
18860 Reported by Zack Weinberg.

18865 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
18866 sure not to introduce newlines in at_groups.

18880 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
18881 cross-compilers, too. This undoes some of the most recent change
18884 2002-02-05 Akim Demaille <akim@epita.fr>
18886 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

18906 2002-02-05 Akim Demaille <akim@epita.fr>
18908 * bin/autom4te.in (&parse_args): Implement `frozen files are
18909 optional are the sum of the previous files on the command line'.
18910 Also, pass `--reload-state=' on them, so...
18911 (handle_m4): don't.
18912 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
18913 (M4sh): Rely on M4sugar.
18914 (Autotest, M4sh, M4sugar): Use frozen files.

18938 change AC_INIT default values.
18940 2002-01-29 Akim Demaille <akim@epita.fr>
18942 * tests/torture.at (Configuring subdirectories): Use configure.in,
18943 so that aclocal 1.4 works.
18944 Reported by Alexandre Duret-Lutz and Larry Schmitt.
18946 2002-01-28 Akim Demaille <akim@epita.fr>
18948 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
18951 2002-01-28 Akim Demaille <akim@epita.fr>
18953 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
18954 AUTOTEST_PATH *after* it was set.
18955 Don't put `.' in the PATH: the user should be precise and `./' if
18956 needed. In addition, given that the test suite does some `cd', if
18957 `.' is in the path, the `tested programs' sections will report
18958 programs found in the test suite's directory, while during the
18959 tests (performed in their own directory), these programs are no
18960 longer visible. In other words, the results is confusing and
18962 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.

19006 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
19007 message on invalid options.
19008 * bin/autom4te.in (parse_args): Don't use
19009 Autoconf::General::getopt with non valid options.
19011 2002-01-17 Jim Meyering <meyering@lucent.com>
19013 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
19014 $ac_cv_exeext so we don't use an old, invalid, cached value.
19016 2002-01-11 Akim Demaille <akim@epita.fr>

19030 * doc/autoconf.texi (testsuite Scripts): Adjust.
19031 * tests/Makefile.am (package.m4): New.
19032 EXTRA_DIST it since its a source.
19034 2002-01-06 Akim Demaille <akim@epita.fr>
19036 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
19037 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
19038 and PACKAGE_BUGREPORT from here...
19039 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
19041 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
19042 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
19043 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
19044 * tests/tools.at (autoheader): Adjust.
19045 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
19047 2002-01-06 Akim Demaille <akim@epita.fr>

19060 sometimes needing writable input.
19062 2001-12-17 Jim Meyering <meyering@lucent.com>

19066 2001-12-14 Akim Demaille <akim@epita.fr>
19068 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
19069 trailing files, don't apply `-rf' to files which might not be
19070 created by configure (core, core.*, and *.core), but just `rm -f'.
19071 Suggested by Jonathan Kamens.
19073 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
19075 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
19077 2001-12-14 Akim Demaille <akim@epita.fr>
19079 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
19081 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
19083 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
19084 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
19085 abs_srcdir, top_srcpath to abs_top_srcdir.
19086 (_AC_OUTPUT_FILES): Adjust.
19087 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
19088 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
19089 * tests/wrappl.in, tests/wrapsh.in: Adjust.
19091 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
19093 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
19094 C/Fortran linking on HP/UX, by extracting the Fortran library
19095 search path from the LPATH line in the $F77 -v output.
19097 2001-12-12 Kevin Ryde <user42@zip.com.au>
19099 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
19100 forbidden file descriptors table.
19102 2001-11-26 Akim Demaille <akim@epita.fr>
19104 * bin/autoscan.in (%c_keywords): Build it at top level.
19105 Map to 1 in order to simplify its uses.
19107 2001-11-26 Akim Demaille <akim@epita.fr>
19109 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
19110 Remove $filepath, useless.
19111 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
19112 variables, they are really part of the tokens.
19113 Split the input line on spaces and then look for tokens.
19114 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
19115 because of `lex$U.$(OBJEXT)'.
19116 (&scan_files): Use "@list" instead of join.
19117 * doc/Makefile.am (CLEANFILES): Add *.fns.
19119 2001-11-26 Akim Demaille <akim@epita.fr>
19121 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
19122 Remove, replaced by...
19123 * tests/wrappl.in: Be common for all the Perl executables.
19124 In particular autoscan and autoheader want -I.
19125 * configure.ac: Adjust.
19126 * lib/autoscan/headers: errno.h is portable.
19128 2001-11-26 Akim Demaille <akim@epita.fr>
19130 * bin/autoscan.in (used): New.
19133 2001-11-26 Akim Demaille <akim@epita.fr>
19135 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
19137 (&scan_sh_file): Remove a duplicate pattern.
19138 (&check_configure_ac): Use long options.
19139 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
19141 2001-11-26 Akim Demaille <akim@epita.fr>
19143 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
19144 Before, having a line containing the opening of a multi line
19145 comment made the whole line be ignored.
19147 2001-11-26 Akim Demaille <akim@epita.fr>
19149 * doc/autoconf.texi (Using an Autotest Test Suite): New.
19150 (testsuite Scripts): Be one of its subsection.
19151 (Autotest Logs): New.
19153 2001-11-26 Akim Demaille <akim@epita.fr>
19155 Test groups are now run two directories deeper.
19157 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
19158 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
19160 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
19161 top_srcdir, builddir and top_builddir.
19162 Use `at_*dir' relatively to the directory containing the
19163 suite, use `*dir' when relatively to the current group dir.
19165 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
19167 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
19168 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
19169 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
19172 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
19174 * doc/autoconf.texi (Using System Type): Add an example of `case
19175 $host' usage so people quit using `case $target' everywhere.
19177 2001-11-22 Akim Demaille <akim@epita.fr>
19179 * doc/autoconf.texi (Installation Directory Variables): Englishoes
19180 spotted by Jim Meyering.
19182 2001-11-16 Paul Eggert <eggert@twinsun.com>
19184 This patch implements a `long double' suggestion by Oliver Kiddle.
19186 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
19187 static, to catch errors if the value isn't known at compile-time
19188 and the compiler supports dynamic arrays. Change its name from
19189 `_array_' to `test_array' to avoid potential name clashes.
19190 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
19191 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
19192 better than double. Catch a bug in GCC 2.95.2 x86.
19193 * doc/autoconf.texi (C Compiler): Document the above.
19196 2001-11-13 Akim Demaille <akim@epita.fr>
19198 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
19200 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
19202 2001-11-13 Akim Demaille <akim@epita.fr>
19204 * lib/autotest/general.m4 (AT_INIT): After having run the test
19205 group, go back to the initial directory, not to at_suite_dir.
19207 2001-11-13 Akim Demaille <akim@epita.fr>
19209 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
19210 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
19211 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
19213 (AT_CHECK_CONFIGURE): Use absolute paths.
19214 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
19215 The problem is still the old one: there is no means in M4 (that I
19216 know about) to create a defining macro, because there is no means
19217 to create `$1' etc., therefore, the defining macro ``swallows''
19218 all the arguments meant to the defined macro.
19220 2001-11-13 Akim Demaille <akim@epita.fr>
19222 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
19223 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
19225 * tests/aclocal.m4: Remove, as it is no longer used.
19227 2001-11-13 Akim Demaille <akim@epita.fr>
19229 * lib/autotest/general.m4: Change `tests?' into `groups?' in
19230 variable names when referring to a single test group, or to
19231 `suite' when referring to the whole test suite.
19232 `at_last_test' is removed: m4 compute at_format itself.
19233 (at_stdout, at_stder1, at_stderr): New variables.
19234 (AT_CHECK): Use them.
19236 2001-11-13 Akim Demaille <akim@epita.fr>
19238 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
19240 Create `testsuite.dir/003/run' instead of `testsuite.003'.
19241 Do it as soon as a test fails, don't wait till the end of the test
19243 Don't remove $as_me.[0-9]*, since these files no longer exist.
19245 2001-11-13 Akim Demaille <akim@epita.fr>
19247 * tests/tools.at: Use absolute paths, since we are no longer run
19250 2001-11-13 Akim Demaille <akim@epita.fr>
19252 Now that tests are running in their own private dir, there is no
19253 need to list the files to remove at the end of tests groups.
19255 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
19256 (AT_data_files, at_data_files): Remove.
19257 (AT_CLEANUP, AT_DATA): Simplify.
19259 Remove the group dir if !debug && !failed.
19260 * tests/atspecific.m4: Adjust.
19262 2001-11-13 Akim Demaille <akim@epita.fr>
19264 Start a new layout for Autotest: `testsuite' creates
19265 `testsuite.dir' in which the at-check-line etc. files are to be
19266 found, and `testsuite.dir/003' where the test group 3 is run.
19268 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
19269 at_check_line_file, at_format, at_test_normalized, at_group_dir
19271 Create the directories.
19272 Use absolute paths for at- files.
19273 (AT_CHECK): Adjust.
19275 2001-11-11 Michael Matz <matz@kde.org>
19277 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
19279 (m4_car): Properly quote arguments.
19281 2001-11-13 Akim Demaille <akim@epita.fr>
19283 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
19284 with stricter rules on LIBOBJS.
19286 2001-11-12 Paul Eggert <eggert@twinsun.com>
19288 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
19289 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
19292 2001-11-12 Akim Demaille <akim@epita.fr>
19294 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
19296 2001-11-12 Akim Demaille <akim@epita.fr>
19298 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
19299 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
19300 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
19301 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
19302 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
19303 specify to what the macro should be defined (typically to 1).
19305 2001-11-12 Akim Demaille <akim@epita.fr>
19307 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
19310 2001-11-12 Akim Demaille <akim@epita.fr>
19312 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
19313 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
19314 definition used by Automake where LEX is +/- "${missing} lex" and
19315 `missing' itself contains variables.
19317 2001-11-12 Akim Demaille <akim@epita.fr>
19319 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
19320 Now that M4sh pushes BODY, the comments were output at the end of
19323 2001-11-08 Akim Demaille <akim@epita.fr>
19325 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
19326 that we can trace macros from aclocal.m4.
19327 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
19328 obsoleted, and redirect to the former anyway.
19329 Reported by Ralf Corsepius.
19331 2001-11-08 Akim Demaille <akim@epita.fr>
19333 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
19334 processed only if present.
19335 * tests/torture.at (Configuring subdirectories): Use autoreconf
19336 instead of successive calls to autoconf.
19337 Add a nonexistent subdirectory to exercise the patch above.
19338 Reported by Ralf Corsepius.
19340 2001-11-08 Kevin Ryde <user42@zip.com.au>
19342 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
19343 doesn't accept .S files.
19345 2001-11-07 Akim Demaille <akim@epita.fr>
19347 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
19348 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
19349 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
19350 * bin/autom4te.in (warn_forbidden): New.
19351 (handle_output): Use it.
19352 Read m4_pattern_forbid with messages.
19354 2001-11-05 Akim Demaille <akim@epita.fr>
19356 * bin/autom4te.in (--normalize): Remove.
19357 * lib/autom4te.in: Adjust.
19359 2001-11-05 Akim Demaille <akim@epita.fr>
19361 * tests/Makefile.am (testsuite): Rename this target as...
19362 ($(TESTSUITE)): this.
19365 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
19367 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
19368 the --prefix option, also remove it's argument.
19370 2001-11-05 Akim Demaille <akim@epita.fr>
19372 * doc/autoconf.texi (testsuite Invocation): Update.
19373 (Writing testsuite.at): Update.
19375 2001-11-03 Akim Demaille <akim@epita.fr>
19377 * doc/autoconf.texi: s/@code/@command/ where appropriate.
19379 2001-11-03 Akim Demaille <akim@epita.fr>
19381 * lib/Autom4te/General.pm: (&catfile, &canonfile)
19382 (&file_name_is_absolute): New, wrappers around routines from
19384 Use and export them.
19385 (&find_configure_ac): Optionally take a directory where to look at.
19386 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
19388 Default @ARGV to `.', not find_configure_ac.
19389 (&autoreconf): Argument is a directory.
19390 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
19391 * doc/autoconf.texi (autoreconf Invocation): Update.
19393 2001-11-03 Akim Demaille <akim@epita.fr>
19395 * lib/Autom4te/General.pm (@export_vars, @export_subs)
19396 (@export_forward_subs): New.
19397 Add basename, dirname, and fileparse.
19399 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
19400 Don't look for aclocal flags if we already know aclocal is not
19402 Move aclocal.m4t only if it exists.
19403 Reported by Ezra Peisach.
19405 2001-11-03 Akim Demaille <akim@epita.fr>
19407 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
19408 passed on command line, defaulting to ./configure.ac if present.
19409 (&maybe_autoreconf, File::Find): Remove, unused.
19410 (&autoreconf): If autoconf is not used, don't try to trace.
19412 2001-11-02 Akim Demaille <akim@epita.fr>
19414 * configure.ac: Bump to 2.52g.
19416 2001-11-02 Akim Demaille <akim@epita.fr>
19420 2001-11-02 Akim Demaille <akim@epita.fr>
19422 * config/config.guess, config/config.sub, doc/standards.texi:
19423 * config/lispdir.m4: Update from masters.
19424 * configure.ac: Bump to 2.52f.
19426 2001-11-02 Akim Demaille <akim@epita.fr>
19428 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
19429 Don't run aclocal when aclocal.m4 is not from aclocal.
19431 Don't run libtoolize and gettextize if --install is not given.
19433 2001-11-01 Paul Eggert <eggert@twinsun.com>
19435 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
19436 be invoked before _AS_LINENO_PREPARE.
19437 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
19438 than character ranges.
19440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
19441 invoking AS_BASENAME. Set the locale variables to 'C' if
19442 possible, as POSIX requires this to get the traditional
19444 * doc/autoconf.texi (Special Shell Variables): Describe the above.
19446 2001-10-31 Paul Eggert <eggert@twinsun.com>
19448 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
19449 with {}, as that triggers a bug in Bash 2.05.
19451 (_AS_LINENO_PREPARE): Use Sed rather than
19452 Awk. Fix the sed prepass to work even if there are multiple
19453 instances of $LINENO on the same line. Do not substitute for
19454 other variables like $LINENOT. Do not check file dates; such a
19455 check is unreliable on sufficiently fast machines, and removing
19456 the check makes the code simpler and more reliable. Check for
19457 output and chmod failures.
19459 * doc/autoconf.texi (Special Shell Variables): Document
19462 2001-10-31 Akim Demaille <akim@epita.fr>
19464 * tests/Makefile.am (atconfig): Remove this target, Automake
19467 2001-10-31 Akim Demaille <akim@epita.fr>
19469 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
19470 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
19471 provided, while it is optional.
19472 * configure.ac: Adjust.
19474 2001-10-26 Paul Eggert <eggert@twinsun.com>
19476 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
19477 lib/Autom4te/Struct.pm:
19478 Require Perl 5.005_03 instead of just 5.005, as some tests fail
19481 * doc/autoconf.texi (Special Shell Variables): Document some
19482 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
19484 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
19485 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
19486 eval $LINENO is not portable in practice.
19488 2001-10-24 Akim Demaille <akim@epita.fr>
19490 * lib/Autom4te/General.pm (backname): New.
19492 2001-10-24 Akim Demaille <akim@epita.fr>
19494 * m4/: Remove, merged into...
19497 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
19499 * doc/autoconf.texi (Shellology): Mention the problems with bash
19500 2.05's use of ANSI quoting in its `set' builtin.
19502 2001-10-22 Paul Eggert <eggert@twinsun.com>
19504 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
19505 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
19506 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
19507 POSIX decided to standardize on the int flavor of strerror_r.
19508 Always do char* test, as there's no reason not to.
19509 Assign to a char* var, to catch strerror_r that returns int*.
19511 * doc/autoconf.texi (Particular Functions):
19512 Document the above changes. Also, document the fact that
19513 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
19515 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
19517 2001-10-20 Akim Demaille <akim@epita.fr>
19519 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
19520 the executable was missing from the log.
19522 2001-10-20 Akim Demaille <akim@epita.fr>
19524 * lib/Autom4te/General.pm (&update_file): If destination is
19525 unchanged, remove the source.
19526 (&up_to_date_p): Don't be verbose, be debug.
19527 * bin/autoreconf.in: No longer support --m4dir.
19528 (&autoreconf): Display the full path of the configure.ac we are
19530 Trace it only once.
19531 Be sure to honor --force with gettextize.
19532 Always run aclocal.
19533 * doc/autoconf.texi: Adjust.
19535 2001-10-20 Akim Demaille <akim@epita.fr>
19537 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
19539 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
19540 `intl' is already present, as it refuses unless --force.
19541 (&parse_args): Use -I, --include instead of the old Autoconf
19543 ($localdir, $autoconf_dir): Remove.
19545 (&maybe_autoreconf): New, to preserve $_ for File::Find.
19547 2001-10-19 Jens Petersen <petersen@redhat.com>
19549 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

19559 2001-10-19 Akim Demaille <akim@epita.fr>
19561 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
19562 comment, explain how to install automatic mode selection.
19565 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
19567 * bin/autoreconf.in (autoreconf): Display the path to the
19568 configure.ac being studied.

20029 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
20031 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
20032 already have $file). Set output files to binary mode (helps avoid
20033 CR issues on DOSish systems).
20035 2001-09-19 Akim Demaille <akim@epita.fr>
20037 * lib/autotest/general.m4: Englishoes.
20038 From Tim Van Holder and Alexey Mahotkin.
20040 2001-09-18 Paul Eggert <eggert@twinsun.com>
20042 * doc/autoconf.texi (Common Shell Constructs): New node,
20043 documenting AS_DIRNAME.
20044 (Limitations of Usual Tools): Refer to it when discussing dirname.
20045 Also, update discussion of POSIX standard to reflect latest draft.
20047 * lib/autoconf/c.m4:
20048 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
20050 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
20051 Do not pass a first argument with leading '-'
20052 to expr, by parenthesizing initial integers that might be negative.
20054 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
20055 now merely checks whether it is an error to pass an argument
20058 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
20059 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
20060 whether it is a (compile-time) error to pass an argument to
20061 getpgrp. This simpler test supports the revised documentation,
20062 and is all that AC_FUNC_GETPGRP's users really need.
20064 2001-09-18 Akim Demaille <akim@epita.fr>
20066 * doc/autoconf.texi (Limitations of Make) <$<>: New.

20076 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
20078 Add test for AS_BASENAME.
20079 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
20080 added test. It now correctly handles /1/2/3/, returning '3' not ''.
20081 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
20082 * tests/base.at: Fixed the expected responses. The old ones were
20084 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
20085 the documentation claims it should (and how it behaved in 2.13).
20087 2001-09-18 Akim Demaille <akim@epita.fr>
20089 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
20090 the AC_CONFIG_COMMANDS invocation.
20091 This also solves the name clash problems.
20092 Don't set the package's ID.
20093 * lib/m4sugar/Makefile.am (version.m4): Revamp.
20094 No longer to be shipped.
20095 (version.in): Remove.

20097 * lib/autoconf/status.m4: Adjust.
20098 Use `m4_PACKAGE_STRING'.
20099 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
20100 the only optional argument is the name of the test suite.
20101 Expect `package.m4' to define the package signature.
20102 * lib/autom4te.in (Autotest): Add `package.m4?'.
20103 * tests/Makefile.am (package.m4): New.
20104 * tests/suite.at: ifnames is a victim.
20106 2001-09-18 Akim Demaille <akim@epita.fr>
20108 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
20109 AC_LIBSOURCE, AC_CONFIG_FILES.
20110 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
20111 program version string doesn't match the package's.
20112 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
20115 2001-09-17 Paul Eggert <eggert@twinsun.com>
20117 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
20118 Allow expression to return any value that can fit into unsigned long
20119 (not int, as before). Check for output errors.

20123 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
20124 Always include <stdio.h> and <stdlib.h>. Evaluate
20125 the expression in an extra function before these includes. Call
20126 fprintf "%d" only after ensuring the argument is of type 'int'.
20127 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
20129 2001-09-17 Paul Eggert <eggert@twinsun.com>
20131 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
20132 or CFLAGS=-O5. In that case, the linker has a relaxed view of
20133 fatal errors, and AC_CHECK_LIB causes it to include libraries even
20134 when they don't exist.
20136 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
20137 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
20140 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
20141 version with the version used by fileutils 4.1, except use
20142 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
20145 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
20147 2001-09-13 Akim Demaille <akim@epita.fr>

20187 * lib/autotest/general.m4 (AT_INIT): Create and remove
20188 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
20189 test suites can cohabit.
20191 2001-09-13 Akim Demaille <akim@epita.fr>
20193 * tests/mktests.sh: Don't output banners for empty test files.

20245 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

20248 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

20292 to avoid GCC warnings.
20295 2001-09-05 Akim Demaille <akim@epita.fr>

20299 2001-09-05 Akim Demaille <akim@epita.fr>
20301 Be ready to handle filenames as stupid as `dnl.at', for if even
20302 the maintainer is dumb enough to do that...
20304 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
20305 excellence in M4 quotation: consider `__file__' is active.
20307 And BTW, when invoking m4, pass the --include in the right order:
20310 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to

20338 New, extracted from main.
20339 Use IO::File wherever possible.

20342 Don't invoke `_au_disable', since ac was not loaded, but just

20370 2001-08-31 Akim Demaille <akim@epita.fr>
20372 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
20373 (testsuite Scripts): There is no such thing as `atconfig.in'.
20374 And actually one diagram is missing: test suite runtime.
20376 2001-08-31 Akim Demaille <akim@epita.fr>
20378 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
20381 2001-08-31 Akim Demaille <akim@epita.fr>
20383 * bin/autoupdate.in (@include): `installcheck' revealed the path
20384 to m4sugar was lacking!
20386 2001-08-31 Akim Demaille <akim@epita.fr>
20388 * man/Makefile.am (.x.1): We really have to pass
20389 autom4te_perllibdir.

20393 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
20394 debug scripts, in particular passing explicitly listed tests to

20399 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
20400 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
20401 Use directly autom4te, not autoconf.

20443 Drop AC_MACRODIR dead for real.
20444 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
20445 `autoheader: `config.hin' is created'.
20446 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
20448 2001-08-31 Akim Demaille <akim@epita.fr>
20450 * bin/autoheader.in: Rewrite in Perl.

20453 2001-08-31 Akim Demaille <akim@epita.fr>
20455 * bin/autoconf.in (--include, -I): New option.
20456 Map --localdir, --autoconf-dir onto it.
20457 Forward autom4te's options instead of interpreting them.
20458 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
20459 There is no such envvar since the inception of autom4te.cfg.
20460 * bin/autom4te.in (&parse_args): Uniquify `@include'.
20461 * bin/autoupdate.in: Adjust, and perform more control.

20463 * tests/autoconf: Dittowise.
20465 2001-08-31 Akim Demaille <akim@epita.fr>

20472 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
20474 2001-08-31 Akim Demaille <akim@epita.fr>

20480 Pass `autoconf_dir' via options, not via invisible envvars.
20481 * lib/Autom4te/General.pm (&find_peer): Remove.
20482 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
20483 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
20484 * man/Makefile.am: Let help2man rely on PATH instead of trying to
20485 find the executables for it.
20486 * tests/Makefile.am: Major cleanup. Too lazy to document...
20487 * tests/atlocal.in: Remove all the obscure envvar manipulations.
20489 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
20490 indeed related to running the test suite, while passing
20491 --autoconf-dir and others is related to running non installed
20492 Autoconf executables. So don't do that, leave it to...
20493 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,

21060 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
21061 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
21062 * doc/autoconf.texi (C Compiler Characteristics): Update

21065 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
21067 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
21068 magic values from an object file when cross-compiling.
21069 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
21071 2001-08-10 Akim Demaille <akim@epita.fr>
21073 * bin/autom4te.in (&handle_output): Don't use `grep' with side
21075 Suggested by Russ Allbery.
21077 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
21079 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
21080 current $prefix to the sub-configures.
21082 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
21084 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
21085 extension (needed on BeOS). Reported by Guido van Rossum.
21087 2001-08-09 Akim Demaille <akim@epita.fr>
21089 * bin/autom4te.in ($icache): Load it only if older than autom4te.
21091 2001-08-07 Akim Demaille <akim@epita.fr>
21093 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
21095 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
21096 No need to remove the files before and after the each test, before
21097 each test and at the end of the suite is enough.
21098 Display only the children `times', not the shell's.
21099 If the test failed or was skipped, at-times is not available.
21101 2001-08-07 Akim Demaille <akim@epita.fr>
21103 Always produce testsuite.log, including when there are no
21104 failures. This helps getting information on skipped tests, and
21105 duration of the tests. Err, implement the latter btw.
21107 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
21108 Dump information on the first run of each test.
21109 (AT_CLEANUP): Create `at-times' containing the duration of the
21112 2001-08-07 Akim Demaille <akim@epita.fr>
21114 The use of `dumpstat' revealed that `len' was used although it
21115 should not. m4_text_wrap was using it, but in the Autoconf world
21116 where it is legal. Hence (i) test M4sh in its own world, not
21117 Autoconf's, and (ii), ahem, fix the bug :)
21119 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
21120 does not like `' instead of [].
21121 (AT_INIT): Forbid `^_?AT_'.
21122 And don't output such tokens.
21123 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
21124 `script.as', and `autom4te.cache'.
21125 Remove `empty' and `macro' which are no longer used.
21126 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
21127 * tests/m4sugar.at: Use it.
21128 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
21130 2001-08-07 Akim Demaille <akim@epita.fr>
21132 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
21134 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
21136 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
21138 2001-08-04 Akim Demaille <akim@epita.fr>
21140 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
21141 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
21143 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
21144 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
21145 (AC_F77_MAIN): Likewise.
21147 2001-08-04 Akim Demaille <akim@epita.fr>
21149 Don't rely on M4sugar outputting the patterns in files, since we
21150 might process the output _without_ running m4, hence without these
21153 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
21154 * bin/autom4te.in (@Request::includes): Remove, unused.
21155 (@Request::source): Rename as...
21156 (@Request::input): this.
21157 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
21158 (&handle_output): Fetch the patterns from the traces.
21159 `$forbidden' and `$allowed' are constant: use m//o.
21160 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
21161 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
21163 2001-08-04 Akim Demaille <akim@epita.fr>
21165 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
21166 autoconf', i.e., in addition to caching traces, cache the output.
21168 * bin/autom4te.in (Request::cache): Rename as...
21169 (Request::id): this.
21170 ($cache, $icache, $tcache, $ocache): New.
21171 (&handle_m4): Save M4 output in the cache instead of $tmp.
21172 (&handle_output): Adjust.
21173 (&up_to_date_p): Check that the output cache is up to date too.
21174 (top level): Run `&handle_m4' iff force or the cache is invalid.
21175 Run `&handle_output' if the output cache is more recent.
21177 2001-08-04 Akim Demaille <akim@epita.fr>
21179 * bin/autom4te.in ($force): New.
21180 (&parse_args, &print_usage): -f, --force is a new option.
21181 (&handle_output): CPP directives might have spaces after `#'.
21182 (&parse_args): The first file only can be frozen.
21184 2001-08-04 Akim Demaille <akim@epita.fr>
21186 Don't let autom4te compute the `include' traces several times:
21187 first check that the trace cache file is up to date, and then
21188 compare its timestamp with that of the output.
21190 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
21191 the preamble. Don't require 5.005 as Autom4te::General does it,
21192 and better yet (use `use', not `require'!).
21193 * lib/Autom4te/Struct.pm: Rename the last occurrences of
21194 Class::Struct as Autom4te::Struct.
21195 * lib/Autom4te/General.pm (File::stat): Use it.
21196 (&mtime): New, export it.
21197 * bin/autom4te.in: Use it.
21198 Declare `$req' is invalid if it is outdated.
21199 Don't declare it valid before saving it if something went wrong.
21201 2001-08-04 Akim Demaille <akim@epita.fr>
21203 Autom4te shall not encode Autoconf data, and preselecting traces
21204 must be proposed to the users.
21206 * bin/autom4te.in (@required_trace): Remove.
21208 (&parse_args, &print_usage): -p, --preselect is a new option.
21209 (&up_to_date_p): Adjust.

21212 2001-08-04 Akim Demaille <akim@epita.fr>
21214 * tests/tools.at (autoconf --trace: user macros): Check traces on
21215 macros invoked without arguments, and macros invoked with multiple
21218 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>

21223 2001-08-03 Akim Demaille <akim@epita.fr>
21225 * bin/autoconf.in ($@): Work around the usual sh bug.
21228 2001-08-03 Akim Demaille <akim@epita.fr>
21230 Clean up the handling of the M4 builtins tracing exception.
21232 * bin/autom4te.in (Request::request): Don't complete M4 builtins

21235 (@m4_builtin): this.
21236 (%m4_builtin_alternate_name): New.
21237 (&parse_args): Complete the trace requests with alternate names.

21244 m4_if, and m4_wrap.
21246 2001-08-03 Akim Demaille <akim@epita.fr>
21248 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
21249 (m4_divert_pop): Dump the whole diversion stack when a diversion
21251 * bin/autom4te.in (&handle_output): Remember of the first
21252 occurrence of a possibly undefined macro, not the last.
21253 Complain about the possibly undefined macros in the same order as
21254 the appear in the output.
21255 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
21256 * tests/tools.at (autoconf: forbidden tokens, basic)
21257 (autoconf: forbidden tokens, exceptions): No longer sort
21258 autoconf's stderr, as it is now deterministic.
21259 Check that `dnl' is caught.
21261 2001-08-01 Akim Demaille <akim@epita.fr>
21263 * configure.ac: Bump to 2.52c.

21280 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
21281 `END', as `Autom4te::General::END' will be triggered.
21282 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
21283 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
21284 system to run `mv', `rm', and `cmp'.

21288 * lib/Autom4te/General.pm (&unique): New.
